[Right Triangles Only] SOHCAHTOA
[Right Triangles Only] sinθ = opposite over hypotenuse

Step-by-step explanation:

Step 1: Identify Variables

Angle θ = x°

Opposite Leg = 3

Hypotenuse = 8

Step 2: Find x°

Substitute [Sine]: sinx° = 3/8
Inverse trig: x° = sin⁻¹(3/8)
Evaluate: x = 22.0243°
Round: x ≈ 22.0°

2. The perimeter of a rectangle is 72 cm. The width of the rectangle is 16 cm. What is the area of the rectangle?

tresset_1 [31]

ANSWER
320cm ²

STEP BY STEP
2 widths (16) should equal 32, so you should have 40cm left. Divide 40 by 2 to get one length. Length = 20, width = 16.

So to find the area, you multiply length times width. 20 x 16 = 320

The area is 320cm ²
