Question

23. The angles of a triangle are in the ratio 3:7:8. Find the
measure of each of the angles.​

Answer 1

Answer:

30° , 70° , 80°

Step-by-step explanation:

The angles of a triangle are in the ratio 3:7:8

Let ratio constant be x

1st angle is 3x, 2nd angle is 7x and 3rd angle is 8x

We know, sum of three angles of a triangle is 180°

ATP,

3x + 7x + 8x = 180°

18x = 180°

x= 180°/18

x= 10°

1st angle is 3x = 3× 10° = 30°

2nd angle is 7x = 7 × 10° = 70°

3rd angle is 8x = 8 ×10° = 80°

Answer 2

Answer:

30 70 80

Step-by-step explanation:

sum of the ratios

3x+7x+8x=18x

so 18x =180

x=10

so first angle is 10 *3=30

second angle is 10*7=70

third angle is 10*8=80
