Find the missing side. Round to<br> the nearest tenth.<br> Х<br> 28°<br> 15<br> x = [?]
Effectus [21]

Given:

The right triangle with base 15 and hypotenuse x.

The measure of angle between base and hypotenuse is 28 degrees.

To find:

The value of x.

Solution:

In a right angle triangle,

\cos \theta=\dfrac{Base}{Hypotenuse}

In the given triangle,

\cos 28^\circ=\dfrac{15}{x}

x=\dfrac{15}{\cos 28^\circ}

x=\dfrac{15}{0.8829476}

x=16.98855

Round the value to the nearest tenth.

x\approx 17.0

Therefore, the value of x is 17.0 units.
