Question

Find the interior angles of a triangle if they are in the ratio:
a. 1: 1:2
b. 2:2:2
c. 2:3: 4 ​

Answer 1

Answer:

sum of angles of triangle = 180°

a) 1:1:2 = 180°

1x + 1x + 2x = 180

4x = 180°

x = 180°/4

x = 45°

1x = 45° X 1 = 45°

2x = 45° X 2 = 90°

so, the interior angles are 45°, 45°, 90°

b) 2:2:2 = 180°

2x + 2x + 2x = 180°

6x = 180°

x = 180°/6

x = 30°

2x = 30° X 2 = 60°

so, the interior angles are 60°,60°,60°

c) 2:3:4 = 180°

2x + 3x + 4x = 180°

9x = 180°

x = 180°/9

x = 20°

2x = 40°

3x = 60°

4x = 80°
