Problema Solution
The first angle of a triangle is half the measure of the second angle. The third angle is 20 degrees less thatn the first angle. Find the measures of all three angles.
Answer provided by our tutors
x + 2x + x - 20 = 200
4x = 200
x = 50
So the three angles are x, 2x and (x-20); 50, 100, 30
