-90 = -2(6a – 3)<br> Pls help just solving an equation. :)

Ksenya-84 [330]

Answer:

a=8

Step-by-step explanation:

We are asked to solve this equation -90=-2(6a-3) . As here our variable is a , we will solve it for a. Let us do it step by step

1. Opening the brackets and distribution of -2 inside

-90=-12a+6

2. Subtracting 6 from both sides we get

-90-6=-12a+6-6

-96=-12a

3. Dividing both sides by 12 we get

$\frac{-96}{-12}=\frac{-12a}{-12}$

$a=8$

If the radius of a circle is 10 feet, how long is the arc subtended by an angle measuring 81°?

gavmur [86]

If the angle is mesure in RADIANS then the arc is given by r. So first convert 81 degrees to radians, then multiply by r which is 10 x 81=810
