Find the value of x and round to the nearest tenth, im good with all other trigonometry

Given:

Right triangle with base 12 cm and height is x.

θ = 35°

To find:

The value of x.

Solution:

Base = Adjacent side = 12 cm

Height = Opposite side = x

Using basic trigonometric ratio formula:

The value of tan 35° = 0.7

Multiply by 12 on both sides.

The value of x is 8.4 cm.

a negative exponent is translated as follows:

so, we have
