Question

two angles of a triangle are the same size. the third angle is 12 degrees smaller than the first angle. find the measure of the angles

Answer 1

STEP 1: Define x:

Let one of two angles of the same size be x

Therefore, the other different one will be x - 12

.................................................................................................

STEP 2: Find x:

Sum of angles in a triangle is 180°

x + x + (x - 12) = 180

x + x + x - 12 = 180

3x - 12 = 180

3x = 192

x = 64

.................................................................................................

STEP 3: Find the 3rd angle

x - 2 = 64 - 12 = 52

................................................................................................

The angles are 64, 64 and 52
