Two acute angle of a right angle traingle are in ratio 11:4
A triangle: 180 degrees
right angle = 90 degrees.
180 = 90 + 11x + 4x
180 = 90 + 15x
90 = 15x
Find x and then substitute into
11x and 4x to find the size of the angles.
Check your work by adding these two angles to 90 to see if it adds to 180.
