Problema Solution

in a triangle the measure of the 1st angle is twice the measure of the second angle. the measure of the 3rd angle is 20 more than the measure of the second angle. what are the meashurments of each angle

Answer provided by our tutors

Let

x = the measure of the second angle

2x = the measure of the first angle

x + 20 = the measure of the third angle

x + 2x + x + 20 = 180

........

x = 40 degrees

2x = 2*40 = 80 degrees

x + 20 = 40 + 20 = 60 degrees

The measurements of the three angles in the triangle are: 40 degrees, 80 degrees and 60 degrees.
