The measure of the three angles are 46, 42 and 92 degrees respectively
Sum of angles in a triangleA triangle is a shape that has 3sides and angles
Let the measure of the angles be x, y and z
If the second angle of a triangle is 4 less than the first angle, then;
y = x - 4
If the third angle is two times the first, then z = 2x
Since the sum of interior angle is 180 degrees, hence;
x + y + z = 180
x +x - 4 + 2x = 180
4x = 184
x = 46
Second angle = x - 4
Second angle = 42 degrees
Third angle = 2(46) = 92 degrees
Hence the measure of the three angles are 46, 42 and 92 degrees respectively

How would paying off the lowest outstanding balance credit card first be beneficial over paying off the one with the highest
interest rate?
Answer:
NOT: Actually paying the one with the highest interest rate is logically the right thing to do, because you can shorten the amount that you spent on interest or charges by month, but paying off the lowest outstanding balance credit card first makes sense if you could transfer the interest balance which is the highest ...
Step-by-step explanation:
Answer:
Pay at least the minimum payment on all credit cards each month to avoid penalties. After that, work toward paying off the debt on the card with the highest interest rate. While some advocate for paying off your smallest debt first because it seems easier, you’ll save more on interest over time by chipping away at high-interest debt.

Find the circumference and the area of a circle with radius 9m.
Use the value 3.14 for pi, and do not round your answers. Be sure to include the correct units in your answers.
The circumference and the area of a circle with a radius of 9m is 28.26
How to find the circumference
The circumference of a circle is its perimeter or distance around it. It is denoted by C in math formulas and has units of distance, such as millimeters (mm), centimeters (cm), meters (m), or inches (in). It is related to the radius, diameter, and pi using the following equations:
Given that:
Circumference of Circle = [tex]2\pi r[/tex]
[tex]9x=28.26[/tex]
[tex]9*3.14=28.26c[/tex]
[tex]or[/tex] [tex]28.26c[/tex] ÷ [tex]\pi(3.14)=9r[/tex]

Shira plants carrots in 4/10 of her garden and potatoes in 25/100 of her garden she wants to know what fraction of her garden has carrots and potatoes
Answer:
In the white box with the "?" PUT 40
final answer: 13/20
Step-by-step explanation:
4/10 + 25/100
can only be added if you find a common denominator. That is the step being asked for on your screen. 4/10 is the same as 40/100.
4/10 + 25/100
= 40/100 + 25/100
Keep the bottom, add the tops.
= (40+25)/100
= 65/100
always simplify when possible. 5 goes into both 65 and also 100
65/100
= 13/20
13/20 of Shira's garden is planted with carrots and potatoes.

Step-by-step explanation:
Firstly find the area if the parallelogram which is
=length of the base × vertical height
=
[tex]12m \times 5m[/tex]
=
[tex]60 {m}^{2} [/tex]
Now solve for the area of the circle
=
[tex]\pi {r}^{2} [/tex]
RADIUS = DIAMETER ÷2
[tex] \frac{4m}{2} [/tex]
=
[tex]2m[/tex]
so the area of the circle
=
[tex] \frac{22}{7} \times 2m \times 2m[/tex]
[tex] \frac{22}{7} \times 4 {m}^{2} [/tex]
[tex]12.57 {m}^{2} [/tex]
subtract the area of the circle from the parallelogram
=
[tex]60 {m }^{2} - 12.57 {m}^{2} [/tex]
=

Determine the equation of the line passing through the points (−1,1) and (1,7).
Write the line in standard form Ax+By=C.
Answer:
[tex]3x - y = -4[/tex]
Step-by-step explanation:
To make things easier, let's first find the equation in slope-intercept form ([tex]y = mx + b[/tex] where m is the slope and b is the y-intercept.
1. Find the slope:
[tex]\frac{7 - 1}{1 - (-1)} = \frac{6}{2} = 3[/tex]
2. Find the y-intercept by plugging in (-1,1) into the equation [tex]y = 3x + b[/tex]
[tex]1 = 3(-1) + b[/tex]
so [tex]b[/tex] = 4
3. Therefore the equation of the line in slope-intercept form is [tex]y = 3x + 4[/tex]
4. To convert slope-intercept form into standard form, let's move the 3x over to the other side and divide by -1 to get rid of the negative.
Our result is [tex]3x - y = -4[/tex].

What is the area of this figure? Please help.
The area of the composite figure can be found by summing the whole area that made up the figure. Therefore, the area of the figure is 213.5m²
Area of a composite figureThe area of the composite figure is the sum of the area of the whole figure.
Therefore, the composite figure can be divided into 2 triangles and two rectangles.
Hence,
area of triangle1 = 1 / 2 × 10 × 13 = 65 m²
area of the triangle2 = 1 / 2 × 15 × 7 = 52.5 m²
area of the rectangle1 = 8 × 3 = 24 m²
area of rectangle2 = 7 × 6 = 42 m²
area of rectangle3 = 5 × 6 = 30 m²
Therefore,
area of the composite figure = 65 + 52.5 + 24 + 42 + 30 = 213.5 meters squared

What is the value of x
Answer:
x = 24
Step-by-step explanation:
Sinθ = opposite side / hypotenuse
Sin30° = AB/BC
½ = 12/x
x = 12 × 2
x = 24
Answer:
x = 24
Step-by-step explanation:
SOH (Sin = Opposite/Hypotenuse)
CAH (Cos = Adjacent/Hypotenuse)
TOA (Tan = Oppositie/Adjacent)
The angle 30 degrees is given. The two values we have are 12 and x. 12 is opposite of the angle and x is on the hypotenuse of the triangle. Because we know this, we can plug those values into one of our formulas from earlier. This gives us the formula for sine.
Sin(30) = 12/x
Plug Sin(30) into your calculator. This gives you the value Sin(30) = 0.5
0.5 = 12/x
Multiply each side by x
0.5x = 12
Divide off 0.5 from both sides
x = 24
