180=interior angle of triangle so
angle TRS IS 180-9X as it is (angles on a straight line)
then angle RTS=5x
and angle TSR=9+x
180=180-9x+5x+9+x
180=-3x+189
180-189=-3x
-9=-3x
x=-9/-3
x=3

Answer:
A = 78.5
Step-by-step explanation:
to find the area of a quarter of a circle, find the area of the whole circle and divide it by 4:
A = (π) ÷ 4
A = (3.14 x ) ÷ 4
A = (3.14 x 100) ÷ 4
A = 314 ÷ 4
A = 78.5
