45° TRIANGLE
45°
45°
5.08 ft. (Height to eyes.)
24 ft. (Leg)
24 ft. (leg)29.08
ft.(Total height)
Trig approximation-
Tan45=x 24
X= 24
Height = 24 + 5.08= 29.08
Special Right Triangle-
Leg= Leg
24 ft. = 24 ft.
Height= 24 + 5.08 = 29.08
30, 42FT
42 ft 30°
Tan30=A/42≈24.25 cos30=42/h≈36.37 90-30=60°

Special Right Triangle-
Short leg= Short leg X √3 Leg
Hyp=Short leg X 2
24 ft. = 24 ft.
Height= 24 + 5.08 = 29.08
14 x 14√3 ≈ 339.48
Height= 14√3 + 5.25 = 29.50
5.25 ft. (Height to eyes.)
30°
14 ft. (Short Leg)
14√3 ft. (long leg)
29.50 ft.(Total height)
Trig approximation-
Tan 60=x 14
X= 24.25
Height = 24.25 + 5.25= 29.08
