Question

The angles of a triangle are in the ratio 3:7: 8. Find the greatest and the smallest angles.
The sum of the angles of a triangle is 180º.​

Answer 1

Answer:

let angles be 3x, 7x, 8x

3x+7x+8x=180°

18x=180°

x=10°

largest angle=8*10°=80°

smallest angle=3*10°=30°

Answer 2

Answer:

Step-by-step explanation:

7x+3x+8x=180

18x=180

x=180/18

x=10

7*10=70

8*10=80

3*10=30

therefore, 80 is the greatest and 30 is the smallest.
