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
