Question

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

Answer 1

Answer:

X = 38.7°

Step-by-step explanation:

Reference angle = x

Opposite side length = 8 cm

Adjacent side length = 10 cm

Applying trigonometric ratio formula, we have:

$tan(x) = \frac{8}{10}$

$x = tan^{-1}(\frac{8}{10})$

$x = 38.7$

x = 38.7° (to the nearest tenth)
