Use the relationship in the diagrams below to solve for x. show all work.

a. x = 24

b. x = 40

Step-by-step explanation:

a.

You are given a right triangle, so use the Pythagorean theorem

a^2 + b^2 = c^2

x^2 + 18^2 = 30^2

x^2 + 324 = 900

x^2 = 576

x = 24

b.

The sum of the measures of all angles is 360 degrees.

x + 2x + 2x + 20 + 3x + 20 = 360

8x + 40 = 360

8x = 320

x = 40

point a is the center of the circle that passes through points e, f, and g and the center of the circle that passes through points x, y, and z.
