Question

a pentagon has 2 angles of 150 two of x and one of (x+30)

Answer 1

Answer:

Here's your answer

Step-by-step explanation:

The sum of the exterior angles of a polygon is always equal to 360°.

So each exterior angle will be 360°/5 = 72°. And each interior angle will be (180 - 72)° = 108°.

The sum of the interior angles in pentagon = 108° × 5 = 540°.

Two angles are 150° and 120° and they add upto 270°.

The remaining angles for the rest is (540 - 270)° = 270°.

Each of three angles = 90°.

This could have been arrived by using formula too provided one remembers it.

Verification: 90° + 90° + 90° + 120° + 150° = 540°
