I need help ASAP, please help!

Answer 1

Given:

m∠R = 90° and m∠Q = 6°

PQ = 2.2 ft and RP = x

To find:

The length of RP.

Solution:

Using basic trigonometric formula:

$\sin \theta=\frac{\text { Opposite of } \theta}{\text { Hypotenuse }}$

$\sin 6^{\circ}=\frac{x}{2.2}$

Multiply by 2.2 on both sides.

$0.1 \times 2.2=\frac{x}{2.2} \times 2.2$

$0.22=x$

$0.2=x$ (nearest tenth)

The length of RP is 0.2 feet.
