Question 71

The diagram shows a right-angled triangle. All of the angles are in degrees.

A right-angled triangle with a vertical side on the left and a horizontal base. The top angle is labeled 3x. The bottom-right angle is labeled 2x + 10. A small square at the bottom-left vertex indicates a right angle.

Find the value of size of the smallest angle in the triangle.
