The second angle in a triangle is one third as large as the first. The third angle is two thirds as large as the first angle. Find the angle measures.

Answer 1

S=F/3

T= (2/3)F

F+S+T = 180

F+ F/3 + 2F/3 = 180

2F =180

F = 90 = first angle

S=90/3 = 30 = 2nd angle

T = 2/3 of 90 = 60 = 3rd angle

It's a right triangle 30-60-90 degrees

or pi/6-pi/3 and pi/2 angles
