What are the values of X, Please give me an in-depth explanation so that I can answer similar problems on my own

You're on your own bud I got no idea.

Step-by-step explanation:

Step-by-step explanation:

a line is 180°

180-90 (given) = 90

so there two angles x and 2x added together equal 90

2x + x = 90

3x = 90

x = 30

the angles are 30 and 2(30)= 60

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units
