Question

b) The angles of a triangle are in the ratio 3:7: 8. Find the greatest and the smallest angles​

Answer 1

Answer:

Largest angle = 80°

Smallest Angle = 30°

Step-by-step explanation:

Ratio = 3:7:8

Sum of angles in triangle = 180°

= 3x + 7x + 8x = 180

18x = 180

x = 10

First Angle = 3 × 10 = 30°

Second angle = 7 × 10 = 70°

Third Angle = 8 × 10 = 80°

Largest angle = 80°

Smallest Angle = 30°

Answer 2

Answer:

3x+7x+8x=180

18x=180

x=10

therefore 3x=30

7x=70

8x=80

greatest angle=80°

smallest angle=30°
