Answer:
9.43
Step-by-step explanation:
find the area of the circle and take away 1/4 of the area (because the angle taken away is 90) then you have the answer.
If we know that line 
is equal to line 
, then this means that ∠
has to be equal to ∠
in order to form a closed triangle. All angle measures of a triangle add up to 
°, so use the equation: 
.
70 + x = 180
Subtract 70 from both sides to isolate x:
180 - 70 = 110
110 = x
Hope this helped.
