Answer 2

Answer:

x = 140°

Explanation:

This is a pentagon

The sum of all angles in pentagon will always be 540°.

This pentagon is sitting on a straight line and the outer angle of two points in given.

The angle over a straight line is always 180°

So, 180 - 60 = 120°

and 180 - 70 = 110°

The given angle is 30°

The other two angles are marked with two semi circles and are named as x. That signifies them as equal.

So, Total sum 540 - (Sum of all known angles 120+110+30) = 280

As we know that two remaining angles are equal.

x = 280/2 = 140°
