Answer:

20

Step-by-step explanation:

Altitudes create 90 degree angles, so if one side is (4x + 10)°, the other must be as well.

Now, set (4x + 10)° equal to 90° to solve for x.

Solve like so:

4x + 10 = 90

-10 from each side

4x = 80

/4 from each side

x = 20

If you want to check:

4x + 10 = 90

4(20) + 10 = 90

80 + 10 = 90

90 = 90
