One angle in a triangle is 18° more than the smallest angle in the triangle, while the other angle is 36° more than the smallest angle. Find the measures of the three angles
------------------------------------------------------------ 

Let x be the measure of the smallest angle in degrees.

The the measure of the first angle is x + 18°, and the measure of the other angle is x + 36°.

Since the sum of interior angles of any triangle is 180°, you have an equation

x + (x + 18) + (x + 36) = 180,   or

3x = 180 - 18 - 36,

3x = 126,

x =  = 42.

Thus the measure of the smallest angle is 42°.

Now find yourself other angles.
