Question

if one angle of a triangle is 80 and the other two angles are in the ratio 3:7 then find the angles
​

Answer 1

Answer:

30 deg ,70 deg

Step-by-step explanation:

As 1angle is 80

So a+b =100

3x+7x=100

X=10 so 30dwg and 70 deg

Answer 2

Answer

Let ratios be = 3x , 7x

One Angle = 80°

Step-by-step explanation:

1 + 2 + 3 = 180° (Angle Sum Property)

3x + 7x + 80° = 180°

10x = 180 - 80

x = 100/10

x = 10

Hence Angles are →

3x = 3 × 10 = 30°

7x = 7 × 10 = 70°
