Answer:

Step-by-step explanation:

Well, first of all the two angles listed on the diagram are alternate exterior angles. Since they are alt exterior angles, they must be congruent to one another. Congruent means: equal or the same.

1. So first I am going to form an equation.

(9x - 5) = (7x - 25)

2. Then I am going to solve.

(9x - 5) = (7x - 25)

3. First, I am going to add 5 from both sides and solve.

(9x - 5) = (7x - 25)

+5 +5

--------------------------

9x = 7x - 30

4. Now I am going to subtract 7x from both sides.

9x = 7x - 30

- 7x -7x

---------------------

2x = 30

5. I am going to divide 2 from both sides, thus making x = 15

2x - 30

÷ 2 ÷ 2

--------------

x = 15 ( This is x, now all you have to do is plug this into each identified angle.

So, the first identified angle is 130 degrees

The second one is also 130 degrees.

Remember, they are congruent so they have the same number (degrees

Mashcka [7]

Answer:

7. Approximately 402.7 inches or 2pi times 64

8. 31.83 To solve this you know 2pi r is an equation for the radius. 2πr=200 and r=200/2π=100/π= 31.83.

9. The one with pi in the equation because 3.14 is only a piece of pi but the symbol represents the whole number which goes on forever.

gregori [183]

Answer:

so, the figure here is a cylinder with a semi sphere on the top, we know the height of whole structure, and the radius of the semi sphere, which is the same as the radius of the cylinder (you can see it because the radius of the semisphere is constant, and you can thin on it as half a sphere over a cylinder).

First, the cylinder will be the structure without the semi sphere, so his height will be te total height minus the radius of the semi sphere, which is 0.9μm.

so now we know the height and the radius of the cylinder, the surface or the sides of it is 2*3.14*r*h = 2*3.14*0.9μm*0.1μm = 0.5662 $μm^{2}$ .
