Question

Watch a tutorial One angle of a triangle measures 80°. The other two angles are in a ratio of 2:3. What are the measures of those two angles?​

Answer 1

Answer:

Let first angle = 80°

Second angle = 2x

Third angle = 3x

Sum of all angles of a triangle = 180°

80° + 2x + 3x = 180°

80° + 5x = 180°

5x = 180° - 80°

5x = 100°

x = 20°

Second angle 2x = 2(20) = 40°

Third angle 3x = 3(20) = 60°
