Question

The ratio of an Isoceles 7:6:7, find the base angles
Isoceles (2 sides equal that the base)​

Answer 1

Answer:

Taking 7:6:7 as ratio of angles.

Let the angles be 7x, 6x, 7x.

Now sum of all angles is 180 in a ∆.

So, 7x+6x+7x=180°

20x=180°

x=180/20=9°

Now, base angles are equal, so they are both 7x.

Hence, ans is 7x=9×7=63°
