Question

the edge of a tile is trimmed to make it fit along the edge of the shower. the diagram shows the angles that was cut. what is the value of x?​

Answer 1

x° = 77.7°

Explanation:

We know that the interior angles within a quadrilateral add up to 360 degrees. We are provided with two right angles and a third angle of 102.3°. So we must solve to find x.

90 + 90 = 180

102.3 + 180 = 282.3

360 - 282.3 = 77.7

x = 77.7 degrees
