Answer:

x = 20

Step-by-step explanation:

We see that the whole measure angle is equal to 90 degrees. According to Part-Whole-Postulate, if we add the smaller angles, we will get 90 degrees. Knowing this, we can form an equation to find the value of x.

x + 2x + (x + 10) = 90

Now you just solve this equation

x + 2x + x + 10 = 90

4x + 10 = 90

4x = 80

x = 20
