Solve for x!! need asap

x = 19

assume that the line under the triangle is a straight line, and the angle of any straight line = 180°,

collect like-terms

subtract

divide

to make sure of the answer, plug in the equation:

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
