An object is 6m away from the base of a mast. The angle of depression of the object from the top pf the mast is 50o, Find, correct to 2 decimal places, the height of the mast
8.60m
7.51m
7.15m
1.19m
Forklaring
Tan 50o = \(\frac{h}{6}\)
h = 6 tan 50
= 6 x 1.1917
= 7.1505
= 7.15
h = 6 tan 50
= 6 x 1.1917
= 7.1505
= 7.15
