Question

he second of a triangle is 6 more than the first angle. The third angle is 12 less than the first angle. Find all three angles if the sum of their angles is equal to 180°

Answer 1

Let first angle be x

x+x+6+x-12=180°

3x-6=180°

3x=186

x=63°

First angle=63°

Second Angle=69°

Third angle=51°
