Question

If one angel of the triangle is 80 and other tow angle are in ratio 3:7. Find all the angle

Answer 1

Answer:

80,30 and 70

Step-by-step explanation:

By angle sum property,

sum of all angles= 180

Let the other two angles be 3x and 7x

Therefore,

3x+7x+80 = 180

3x+7x = 180- 80

10x = 100

Hence x= 10

First angle = 80 (given)

Second angle = 3*10 = 30

Third angle = 7*10 = 70

HOPE THIS WAS HELPFUL

Answer 2

given angel is 80 and we know a triangle is 180 so 180-80=100
ans other two angle ratio is 3:7 so one angel is 70 degrees and one angel is 30 degrees
so answer is 80,70,30
