Answer:

The length of TR to the nearest tenth of a foot is 4.9 feet.

Step-by-step explanation:

Δ RST is a Right Angle Triangle at

∠ T = 90°

∠ S = 66°

ST =2.2 feet

To Find:

TR = ?

Solution:

In Right Angle Triangle Δ RST we will apply Tangent Rule

[tex]\tan S = \frac{\textrm{side opposite to angle S}}{\textrm{side adjacent to angle S}}\\\\\tan 66= \frac{TR}{ST}\\ \\2.246 = \frac{TR}{2.2} \\\\\therefore TR = 2.246\times 2.2\\\\\therefore TR = 4.941\ feet\\\therefore TR =4.9\ feet[/tex]

The length of TR to the nearest tenth of a foot is 4.9 feet.
