Question

Determine the approximate value of θ.

Group of Answers:

38.7

51.3

36.9

53.1

Answer 1

Explanation:

`tan \theta=(4)/(5) =0.8\\\theta=tan^(-1) (0.8) \approx~38.6598^\circ\\\approx~38.7^\circ`

Answer 2

The answer to your question is 38.7

Explanation:

To solve this problem, we must use trigonometric functions. The picture shows the opposite side and the adjacent side so we must use tangent to find Ф.

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

Opposite side = 4

adjacent side = 5

tan Ф =
`(4)/(5)`

tan Ф = 0.8

tan⁻¹Ф = 38.7°
