Two adjacent angles are inside a 90° angle. One angle has a measure of (x+4)° and the other angle has a measure of (3x+2)° . What is x ?
A 90 degree angle is shown on a white background. A ray is splitting the 90 degree angle into two adjacent angles. The top angle is labeled as x plus 4. The bottom angle is labeled as 3 times x plus 2.

To solve this problem, we can set up an equation based on the fact that the sum of the two adjacent angles should equal 90 degrees.
(x + 4) + (3x + 2) = 90
Combine like terms:
4x + 6 = 90
Subtract 6 from both sides:
4x = 84
Divide both sides by 4:
x = 21
Therefore, x is 21.
