Answer:
Solution given:
angle of elevation [A]=29°
height [p]=?
base[b]=400ft
since
relationship between base and height is given by Tan angle
we have
Tan 29°=opposite/adjacent
Tan29°=perpendicular [P]/base[b]=P/400
P=Tan29*400
P=221.72ft

Answer:
-9, 9
Step-by-step explanation:
a² − 8ab + 16b² = 81
(a - 4b)² = 81 Wrote the left-hand side as a square
a - 4b = ±9 Took the square root of each side
All values of a - 4b are -9 and +9.
Answer:
A
