Answer:
Height of the building = 115.4 ft.
Step-by-step explanation:
Height of building = AB + 46.4 + CD + 30.5
By applying Pythagoras theorem in ΔABP,
(26)² = (10)²+ (AB)²
676 - 100 = AB²
AB² = 576
AB = 24 ft
By applying sine rule in ΔCDE,
cos(60°) = ![\frac{CD}{CE}](https://tex.z-dn.net/?f=%5Cfrac%7BCD%7D%7BCE%7D)
CD = CE × ![\frac{1}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D)
CD = ![\frac{29}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B29%7D%7B2%7D)
CD = 14.5 ft
Total Height = 24 + 46.4 + 14.5 + 30.5
= 115.4 ft
