C should be the correct answer
Answer:

Step-by-step explanation:
The perimeter is the sum of the side lengths.
A rectangle has 4 sides: 2 lengths and 2 widths, so the perimeter formula is

The length is 20 meters and the width is 4 meters.

Multiply.

Add.

The perimeter of the rectangle is <u>48 meters. </u>
A.
h = 14 ft · sin 30° = 14 ft · 0.5 = 7 ft.
b.
From the bottom of the height to the bottom of the slide:
y² = 14² - 7² = 196 - 49 = 147
y = √147 = 12.12 ft
15 ft - 12.12 ft = 2.88 ft ( from the bottom of the stairs to the bottom of the height )
tan x = 7 / 2.88 = 2.43
∠x = tan^(-1) 2.43
∠x = 67.63° ≈ 68°.
Answer:
C) 50 degrees
Step-by-step explanation:
angles x and 130 degrees are supplementary in that they add up to 180 degrees.
x + 180 - 130 = 50 degrees
