Question

the angle of a triangle are in the ratio 3:7:8 the measure of the greatest angle is​

Answer 1

Answer:

Let the unknown Angle be x

Given ratio 3:7:8 ( 3x,7x and 8x)

So the sum of all the three angles in a triangle is = 180

3x + 7x + 8x = 180

18x = 180

X = 10

Therefore all the three angles are

3x = 3(10) = 30 degree

7x = 7(10) = 70 degree

8x = 8(10)=80 degree

Therefore the final answer is the measure of the greatest angle is 80°
