Since the area of a circle is π

, and our radius is 9 we know the total area to be 254.469, and the ratio of sector area to total area is 169.56/254.469 = .6663. There are 360 degrees in a circle, so:

≈ 240°
240 degrees
We can use the distribution method for both sides:
9 (x+2) = 5 - 2( x - 1 )
9x + 18 = 5 -2x + 2
Move like terms to one side and combine:
9x + 2x = 5+2-18.
11x = -11
x = -1.
Answer:
The second step is to mutiply each side by 3
Step-by-step explanation:
h/3 + 7 = 5...Problem
h/3 = 5 - 7...Step 1
h/3 = -2...Simplification of Step 1
h = -6.....step 2
