The shape is a pentagon.
The interior angles of a pentagon always add up to 540°.
When you add up all the labeled angles in the picture, you get (16x + 12).
16x + 12 = 540
16x = 528
X = 33
Step-by-step explanation:
4x-25+3x+25+3x+15+4×+2x-3=360
4x+3x+3x+4x+2x-25+25+15-2=360
16x +12=360
16x=360-12
16×÷16=348÷16
×=21.75

Given that sin θ= 1 / √2, we want to find the value of tan θ.
First, find the value of θ.
Answers
Answer:
value of tan θ = 1
Step-by-step explanation:
To find θ do the asin of 1/√2
θ = asin (1/√2)
θ = asin (0.707106781)
θ = 45
and then to find tan θ, do tan 45
tan 45 = 1
The difference between two numbers is 10 and their sum is 20. Find the biggest number.
Answers
Answer:
15
Step-by-step explanation:
x - y = 10, then x = 10 + y
x + y = 20
substitute for x:
10 + y + y = 20
2y = 10
y = 5
x = 10 + 5 = 15

2x−y=5
Answers
Answer:
x + 2y = -2
Step-by-step explanation:
Well let's examine the relation between x and y in a perpendicular line.
We can use the fact that for a line Ax + By = C, any line with equation Bx + (-A)y = D is perpendicular (swapping A and B gives a mirror image with respect to the line x=y and changing one of the signs gives a mirror image with respect to axis x or y. Those two together give a perpendicular line).
So we're looking for a line with equation x + 2y = D
We know what it passes through the point (6, -4), so let's input it into the equation x + 2y = D
6 + 2*(-4) = D
6 - 8 = D
D = -2
So the equation is x + 2y = -2
note that 2x + 4y = -4
or any other multiple also works.

Answer: x=12
Step-by-step explanation:
We will use the Pythagorean Theorem since we know two sides and it is a right triangle
Pythagorean Theorem is a^2+b^2=c^2
a=5,b=x, c=13
(5)^2+(x)^2=(13)^2
25+(x)^2=169
Subtract 25 from both sides to start solving for x
(x)^2=144
Take the square root of both sides and get x=12
x=12

300$ at 6% for 2 yrs what is the simple interest
Answers
Answer:
Simple interest after 2 year = $36
Step-by-step explanation:
Given:
Amount invested = $300
Number of year amount invested = 2 year
Rate of interest per year = 6% = 6/100 = 0.06
Find:
Simple interest after 2 year
Computation:
Simple interest formula;
Simple interest = [Amount invested][Rate of interest][Number of year]
Simple interest after 2 year = [300][0.06][2]
Simple interest after 2 year = [18][2]
Simple interest after 2 year = $36

The price of a visit to the dentist is $50. If the dentist fills any cavities, an additional charge of $100 per cavity
gets added to the bill.
If the dentist finds n cavities, what will the cost of the visit be?
Answers
Answer:
I believe the answer will be 50+100n dollars
Step-by-step explanation:
n is the number of cavities so however many cavities there is, it gets multiplied by 100, in this case, it is 100*n which is 100n. So your final cost would be 50+100n dollars.
