The area of the park will be 375 ft squared (rectangular shaped park that is)
Answer:
B
Step-by-step explanation:
Plug the values of x into each equation
Area of triangle = 1/2 × base × height
so,
24=1/2*base*4
base=12m
Right triangle, so one angle = 90 and sum of the other 2 angles = 90
so
71x - 1 + 20x = 90
91x = 91
x = 1
<A = 20(1) = 20
answer
<A = 20 degrees
