Question

find the measures of the angels of a triangle if one angle of a triangle is 80 degree and the other 2 angles are in the ratio 3:7​

Answer 1

Answer:

The other two angles are 30° and 70°

Step-by-step explanation:

Let the two angles be 3x and 7x

Now,

In a Triangle,

3x + 7x + 80° = 180° [Angle Sum Property]

10x + 80° = 180°

10x = 180° - 80°

10x = 100°

x = 100/10

x = 10

Thus,

The angles are 3x = 3(10) and 7x = 7(10)

= 30° and 70°

Hence,

The other two angles are 30° and 70°.
