Answer:
60°
Step-by-step explanation:
90°+30°=120°
180°_120°=60°
Answer:
yes
Step-by-step explanation:
y=-16r^2+63r+4
maximum value of y :
y'=0
-32r +63=0
r= 63/32
y = -16(63/32)²+63(63/32)+4
= -4 + 124 + 4 = 124 ft
124 > 68

Find angle y first by setting it equal to 180
With its adjacent angles. Then solve for x by triangle angles
101.65 x .30= 30.50 saving
so take 101.65 - 30.50= 71.15
