Question

Find the missing side length

Answer 1

Answer: 24.24 (24 to the nearest whole number)

Explanation:

Following trigonometric rule,

Tan tita = opposite side/ adjacent side

Tan 68° = 60 / b

2.475 = 60 / b

By cross multiplication,

2.475b = 60

Divide both sides by 2.475

2.475b/2.475 =60/2.475

b = 24.24

Hence, adjacent side = 24.24 (24 to the nearest whole number since opposite side is in whole number).

Answer 2

The answer to your question is b = 148.5

Explanation:

To solve this problem, use trigonometric functions

tan Ф =
`(opposite side)/(adjacent side)`

opposite side = b

adjacent side = 60

tan Ф = tan 68° = 2.48

Opposite side = adjacent side x tan Ф

Opposite side = 60 x 2.48

Opposite side = b = 148.5
