Answer:
Option B.
Step-by-step explanation:
step 1
Find the area of the playground
The area of the playground is equal to the area of a rectangle plus the area of a triangle
step 2
Find the number of bags of wood chips needed
by proportion
step 3
Find the cost
For an isosceles triangle angles ABC=ACB=35
Let the angle ADB be x
then ADC is 180-x
as AD is median so BD=CD
and for isosceles triangle AB=AC
so AB/AC=BD/CD=1
By angle bisector theorem
BAD=CAD=y (just take it)
for an triangle BAD 35+x+y=180...(1)
for an triangle DAC 35+180-x+y=180...(2)
35+y=x
therefore
35+34+y+y=180
2y+70=180
2y=100
y=55
therefore angle BAD=CAD=55
