Answer:
h = 20.3 cm
Step-by-step explanation:
Apply trigonometric ratio formula to find h.
Reference angle = 40°
Opposite side length = 17 cm
Adjacent side = h
Thus:
Tan (40) = 17/h
h × tan (40) = 17/h × h (multiplication property of equality)
h × tan(40) = 17
(h×tan(40)/tan(40) = 17/tan(40) (division property of equality)
h = 20.3 cm (1 decimal place)
