What is the value of x? Enter your answer in the box.
Answer:
x = 61°
Step-by-step explanation:
Property of a triangle,
Sum of interior angles of a triangle = 180°
By applying this property in ΔABC,
m∠A + m∠B + m∠C = 180°
x° + 67° + 52° = 180°
x + 119° = 180°
x = 180 - 119
x = 61°
Therefore, measure of angle A = x = 61°
Which is the solution for 3 (10x+4) = 8(3x + 6)
Answer:
x=6
Step-by-step explanation:
Answer:
3(10x+4)=8(3x+6)
Step 1: Simplify both sides of the equation.
3(10x+4)=8(3x+6)
(3)(10x)+(3)(4)=(8)(3x)+(8)(6)(Distribute)
30x+12=24x+48
Step 2: Subtract 24x from both sides.
30x+12−24x=24x+48−24x
6x+12=48
Step 3: Subtract 12 from both sides.
6x+12−12=48−12
6x=36
Step 4: Divide both sides by 6.
6x = 36
Answer:
x=6
The access code for a car's security system consists of digits. The first digit cannot be and the last digit must be . How many different codes are available?
Complete Question
The access code for a car's security system consists of 6 digits, the first digit cannot be 8 and the last digit must be odd, how many different codes are available
Answer:
There are 450000 possible different codes
Step-by-step explanation:
Given
Code = 6 digits
First = All but 8
Last = Odd
Required
Determine the possible number of codes
Analyzing each individual digit that makes up the code.
First: can be any of 0,1,2,3,4,5,6,7,9 ----- 9 possible numbers
Second, Third, Fourth and Fifth can be any of 0,1,2,3,4,5,6,7,8,9 since there's no restriction ----- 10 possible numbers
Last can be any of: 1,3,5,7,9 ----- 5 possible numbers
So, the number of possible selections is:
[tex]Selection = 9 * 10 * 10 * 10 * 10 *5[/tex]
[tex]Selection = 450000[/tex]
Hence, there are 450000 possible different codes

Use triangle ABC drawn below & only the sides labeled. Find the side of length AB in terms of side a, side b & angle C only. You will need to use both Soh-Cah-Toa and the Pythagorean Theorem to solve for side AB.
Answer:
[tex]AB = \sqrt{a^2 + b^2-2abCos\ C}[/tex]
Step-by-step explanation:
Given:
The above triangle
Required
Solve for AB in terms of a, b and angle C
Considering right angled triangle BOC where O is the point between b-x and x
From BOC, we have that:
[tex]Sin\ C = \frac{h}{a}[/tex]
Make h the subject:
[tex]h = aSin\ C[/tex]
Also, in BOC (Using Pythagoras)
[tex]a^2 = h^2 + x^2[/tex]
Make [tex]x^2[/tex] the subject
[tex]x^2 = a^2 - h^2[/tex]
Substitute [tex]aSin\ C[/tex] for h
[tex]x^2 = a^2 - h^2[/tex] becomes
[tex]x^2 = a^2 - (aSin\ C)^2[/tex]
[tex]x^2 = a^2 - a^2Sin^2\ C[/tex]
Factorize
[tex]x^2 = a^2 (1 - Sin^2\ C)[/tex]
In trigonometry:
[tex]Cos^2C = 1-Sin^2C[/tex]
So, we have that:
[tex]x^2 = a^2 Cos^2\ C[/tex]
Take square roots of both sides
[tex]x= aCos\ C[/tex]
In triangle BOA, applying Pythagoras theorem, we have that:
[tex]AB^2 = h^2 + (b-x)^2[/tex]
Open bracket
[tex]AB^2 = h^2 + b^2-2bx+x^2[/tex]
Substitute [tex]x= aCos\ C[/tex] and [tex]h = aSin\ C[/tex] in [tex]AB^2 = h^2 + b^2-2bx+x^2[/tex]
[tex]AB^2 = h^2 + b^2-2bx+x^2[/tex]
[tex]AB^2 = (aSin\ C)^2 + b^2-2b(aCos\ C)+(aCos\ C)^2[/tex]
Open Bracket
[tex]AB^2 = a^2Sin^2\ C + b^2-2abCos\ C+a^2Cos^2\ C[/tex]
Reorder
[tex]AB^2 = a^2Sin^2\ C +a^2Cos^2\ C + b^2-2abCos\ C[/tex]
Factorize:
[tex]AB^2 = a^2(Sin^2\ C +Cos^2\ C) + b^2-2abCos\ C[/tex]
In trigonometry:
[tex]Sin^2C + Cos^2 = 1[/tex]
So, we have that:
[tex]AB^2 = a^2 * 1 + b^2-2abCos\ C[/tex]
[tex]AB^2 = a^2 + b^2-2abCos\ C[/tex]
Take square roots of both sides
[tex]AB = \sqrt{a^2 + b^2-2abCos\ C}[/tex]

Find the exact value of sin A in simplest radical form.
Answer:
[tex] \sin A= \frac {1} {\sqrt {82}}[/tex]
Step-by-step explanation:
[tex]\sin A= \frac {BC} {BA} \\\\
\sin A= \frac {1} {\sqrt {82}} \\\\[/tex]
The exact value of sin A in simplest radical form is 1 /√82.
What is sine?In trigonometry, the sine function can be defined as the ratio of the length of the opposite side to that of the hypotenuse in a right-angled triangle.
Now from the given triangle we have,
Hypotenuse, AB = √82
Perpendicular, BC = 1
Base, AC = 9
Since, sine function is the ratio of the length of the opposite side to that of the hypotenuse.
Thus, Sin A = Perpendicular / Hypotenuse
⇒ Sin A = 1 /√82
which is the required the exact value of sin A in simplest radical form.
Thus, the exact value of sin A in simplest radical form is 1 /√82

Line b passes through the point ( (6,4) and has a slope of -2. What is the equation of Line b in standard form?
2x + y = -11
x + 2y = -14
x + 2y = -16
2x + y = 16
Answer:
Equation of line b in standard form is: [tex]\mathbf{2x+y=-11}[/tex]
Option A is correct.
Step-by-step explanation:
We need to find equation of line b that passes through the point ( (6,4) and has a slope of -2.
First we need to find y-intercept of line using formula: [tex]y=mx+b[/tex] where m is slope and b is y-intercept.
Using m=-2 , x=6 and y=4 the y-intercept will be:
[tex]y=mx+b\\4=-2(6)+b\\4=12+b\\b=4-12\\b=-11[/tex]
Now finding the equation of line having slope m=-2 and y-intercept b=-11
[tex]y=mx+b\\y=-2x-11[/tex]
Writing the equation in standard form
[tex]y=-2x-11\\2x+y=-11[/tex]
So, equation of line b in standard form is: [tex]\mathbf{2x+y=-11}[/tex]
Option A is correct.

Answer:
each student gets 3 erasers
Step-by-step explanation:
You have to divide 20 total erasers by the 6 students and you get about 3.33... and this number rounded down is 3.
Have an stupendous day! I hope this answer was helpful to you.
Each student get 3 erasers.
What is Division method?
Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications.
For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.
Given that;
Total number of students = 6
Number of erasers = 20
Now,
Since, Total number of students = 6
And, Number of erasers = 20
Hence, Number of eraser getting by each students = 20 ÷ 6
= 3.33
Thus, Each student get 3 erasers.
