Question

NEED HELP ASAP Find the value of x. Round to the nearest tenths place. ​

Answer 1

Answer:

x = 77.8 ft

General Formulas and Concepts:

Pre-Algebra

• Order of Operations: BPEMDAS

Trigonometry

• sin∅ = opposite over hypotenuse

Step-by-step explanation:

Step 1: Define

∅ = 40°

opposite leg of angle = 50 ft

hypotenuse = x ft

Step 2: Solve for x

1. Substitute:                                        sin40° = 50/x
2. Multiply x on both sides:                 xsin40° = 50
3. Divide sin40° on both sides:           x = 50/sin40°
4. Evaluate:                                           x = 77.7862
5. Round:                                              x = 77.8 ft
