Given:

A figure of a right angle triangle.

To find:

The value of x.

Solution:

In a right angle triangle,

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

In the given figure,

\cos C =\dfrac{CD}{CE}

\cos 67^\circ =\dfrac{x}{85}

0.39073\times 85=x

33.21205=x

Round to the nearest tenth.

x\approx 33.2

Therefore, the measure of x is 33.2 units.
