I believe the answer is C, 68.

Angles A and R are supplementary so:
180=x+124
Angle A=56

AFD is an isosceles triangle so angles A and D are both 56. Then you can use these to solve for angle AFD.
180 = x+56+56
x=68

A circular lawn of radius 10 mhas a circular flower bed of radius 5m dug into it.

leva [86]

Answer:

75π $m^{2}$ ≈ 235.62 $m^{2}$

Step-by-step explanation:

R represents the radius of the lawn

r represents the area of the circular bed

So,

Area of the remaining lawn, A = area of the lawn - area of the circular flower bed

A = πR^2 - π^2

A = π(R^2 - r^2)

A = π(10^2 - 5^2)

A = π( 100 - 25)

A = 75π $m^{2}$ ≈ 235.62 $m^{2}$
