.
hind the angle​

Answer 1

Answer:

Step-by-step explanation:

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

Thus the angles are 3x, 7x and 8x.

We know that sum of all angles in triangle = 180°.

=> 3x + 7x + 8x = 180°

=> 18x = 180°

=> x = 180°/18 = 10°.

Thus the angles are 30°, 70° and 80°.

Answer 2

Answer:

30,70,80

Step-by-step explanation:

3x+7x+8x=180[sum of angles of a triangle =180]

or 18x=180

or x=180÷18

x=10

or 3x=30

or 7x=70

or 8x=80
