Firstly, expand the equation.

Next, move the variable x to the left and all the constant to the right.

Then, solve for x.
Answer:
18
Step-by-step explanation:
36/4=9 9/2=4.5 4.5+4.5+4.5+4.5=18
When the radius is 8, the area would be 201.06
Area of circle = pi x radius² (pi x 8²)
Answer:
B. 34.90°
Step-by-step explanation:
✔️First, find GF using Trigonometric function:
Reference angle = 58°
Adjacent length = GF
Hypotenuse = 6 cm
Apply CAH, thus:
Cos 58 = Adj/Hyp
Cos 58 = GF/6
GF = 6*Cos 58
GF = 3.17951558 ≈ 3.18 cm
✔️Find angle K using the Sine Rule:

Substitute

Multiply both sides by 3.18



K = 34.8618741° ≈ 34.90°
Answer:
hypotenuse
Step-by-step explanation:
the other sides are known as legs
