A. because it's a lower chance of you being robbed and getting your money taken away
Same as the last one ! Review your parallel lines, and you'll see that angles A and B have to be equal. So you solve it EXACTLY the same way as the last one.
You say "A equals B", and that means that
8x - 10 = 3x + 90
Solve that to find x (it's 20),
and then use x to find angle B (it's 150; they both are).
(Don't just take my word for it. Please work it through.)
Answer:
27.93 square yard
Step-by-step explanation:
For semicircle:
Radius (r) = 7 yards
For Triangle:
b = 2r = 2*7 = 14 yd
h = 7 yard
Area of shaded region = Area of semicircle - Area of triangle
