ANSWER

x=36.08 units

EXPLANATION

From the given right triangle,x is adjacent to the 49° angle.

The hypotenuse of the right triangle is 55 units.

Recall the mnemonics SOH-CAH-TOA

We use the cosine ratio,

[tex] \cos(49 \degree) = \frac{adjacent}{hypotenuse} [/tex]

[tex]\cos(49 \degree) = \frac {x}{55} [/tex]

Solve for x,

[tex]x = 55\cos(49 \degree) [/tex]

x=36.0832

Rounding to the nearest hundredth,we have

x=36.08
