Question

13. A heptagon has three equal angles each of 120° and four equal angles. Find the site
1. The ratio between an exterior angle and the interior angle of a regular polygon is
of equal angles.​

Answer 1

Answer:

Measure of 4 equal angles will be 135 each.

Step-by-step explanation:

According to the angle sum property

Sum of all angles of hexagon = 900

If three angles are equal take it as x each

And another four angles are equal then take them as y each

So,

3x + 4y = 900

3(120) + 4y = 900 (because x =120)

360+4y = 900

4y = 900-360

4y = 540

y = 540/4

y = 135

Hence, measure of 4 equal angles will be 135 each.
