Question

In the triangle below,
x= [ ? ]°. Round to the nearest
tenth.

Answer 1

X = 38.7°

Explanation:

Reference angle = x

Opposite side length = 8 cm

Adjacent side length = 10 cm

Applying trigonometric ratio formula, we have:

`tan(x) = (8)/(10)`

`x = tan^(-1)((8)/(10))`

`x = 38.7`

x = 38.7° (to the nearest tenth)
