Answer: 228.01 pi and the second is near 715. 9514

Step-by-step explanation: area of a circle is pi times the radius squared. Radius is half a diameter. Half of 30.2 is 15.1. 15.1 squared is 228.01. If you use 3.14 in place of pi, and multiply that to 228.01 you get 715.9514. I think

What is the measure of angle 1?<br> 36°<br> 86°<br> 89°<br> 94°
den301095 [7]

Answer:

94°

Step-by-step explanation:

Remember that the sum of the interior angles of a triangle is 180°. To do it the easier (but longer) way, simply do the following. Add all the interior angles up, and subtract it from 180 to get the angle you do not know, and then solve for angle 1:

180 = (29 + 65 + m∠2)

= 180 - 94 = m∠2  

= m∠2 = 86°

Next, note that ∠1 & ∠2 are directly next to each other. When this occurs, solve for their supplementary angle. We know that m∠2 = 86°. Supplementary Angle = 180°:

180 - 86 = 94°

m∠1 = 94°.

The simpler way to solve this, is to first note that it is a triangle. To solve for the outlier angle, simply add the two opposite angles together to get your answer:

m∠1 = 29 + 65

m∠1 = 94°.

Solve the system of equations below by elimination. Write your answer as an ordered pair. e.g. (2,3)
Lyrx [107]

Answer:

(45,35)

Step-by-step explanation:

1 - Stack the equations on top of each other

3x - 4y = -5

4x + 4y = 40

2 - We can eliminate by subtracting the bottom equation from the top equation

 3x - 4y = -5

- 4x - 4y = 40

3 - The y's cancel out, leaving us with...

 3x = -5

- 4x = 40

4 - Continue simplifying

-1x = -45

5 - We can switch the -1x with -x to make things simple

-x = -45

6 - Positize (make it positive) the statement

x = 45

7 - Halfway there! Substitute the x value into one of the equations

(3 * 45) - 4y = -5

8 - Solve

135 - 4y = -5

Minus 135 on both sides

-4y = -140

Divide by -4 on both sides

y = 35

9 - Here is your answer!!

x = 45

y = 35

(45,35)
