The question does not specify the condition that must satisfy the given angles. We assume they are the internal angles of a triangle.

Answer:

x = 10

Step-by-step explanation:

Internal Angles of a Triangle

The measure of the angles of a triangle are given as 48-x, 9x-38, and 90. Since the sum of the internal angles of a triangle is 180°:

48 - x + 9x - 38 + 90 = 180

Simplifying:

100 + 8x = 180

Subtracting 100:

8x = 180 - 100 = 80

x = 80/8

x = 10
