I need help for real, no helpless answers please!

Given:

m∠R = 90°

m∠Q = 6°

PQ = 2.2 ft

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}$

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

Multiply by 2.2 on both sides.

$$0.1\times2.2=\frac{x}{2.2}\times2.2$

$$0.22=x$

$$0.2=x$ (nearest tenth)

The length of RP is 0.2 feet.

What is the sum of <br> (6x-27)=(3x+15)

STALIN [3.7K]

Answer: 14

Step-by-step explanation: Step 1: Subtract 3x from both sides.

6x−27−3x=3x+15−3x

3x−27=15

Step 2: Add 27 to both sides.

3x−27+27=15+27

3x=42

Step 3: Divide both sides by 3.
