  2. Special Right Triangle- Leg= Leg 24 ft. = 24 ft. Height= 24 + 5.08 = 29.08 Trig approximation- Tan45=x 24 X= 24 Height = 24 + 5.08= 29.08 45° Triangle 45° 24 ft. (leg) 29.08 ft.(Total height) 45° 5.08 ft. (Height to eyes.) 24 ft. (Leg)

  3. 30, 42ft 60° A h 42 ft 30° Tan30=A/42≈24.25 cos30=42/h≈36.37 90-30=60°

  4. Trig approximation- Tan 60=x 14 X= 24.25 Height = 24.25 + 5.25= 29.08 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 60, 14ft 30° 14√3 ft. (long leg) 29.50 ft.(Total height) 60° 5.25 ft. (Height to eyes.) 14 ft. (Short Leg)
