The measure of the angle is 57 degrees

First, we need to know that the sum of the angles in a triangle is equal to 180 degrees

Now, from the diagram shown, we have that the angles are;

2x + 20

X + 10

2X-5

Equate the angles, we have;

2x + 20 + x + 10 + 2x - 5 = 180

collect the like terms, we have;

5x + 25 = 180

5x = 155

Divide by 5

x = 31

Then, the value of the angle is;

= 2(31) - 5

= 62 - 5

= 57 degrees
