Question

Find the value of x to the nearest degree
a. 30
b. 60
c. 70
d. 85

Answer 1

`\tan(\theta) = \frac{\text{opp}}{\text{adj}}`


`\tan(x) = \frac{\text{19}}{\text{11}}`


`x = \tan^(-1) \bigg(\frac{\text{19}}{\text{11}} \bigg)`


`x = 60 \textdegree \text{ (nearest whole number) }`

Answer: Option B

Answer 2

x = arctan(base / height)

x = arctan(19/11)

x = 59.93

x = 60
