Question

the four angle of a pentagon are equal and if the angle measures 140 degree find the measure of four equal angles ​

Answer 1

Step-by-step explanation:

Let equal angles be x

In Pentagon sum of all angles is 540

A/Q. x+x+x+x+140=540

4x = 540-140

4x = 400

x = 100

Answer 2

Question:The four angle of Pentagon are equal and if the angle measures 140° find the measure of four equal angles.

Answer:

100° each

Given:

One angle=140°

To find:

The four equal angles

Solution:-

Let the four angles be x

Then

x+x+x+x+140°=540 {Sum of angles of Pentagon}

4x+140°=540°

4x=540°-140°

4x=400°

x=100°

100°+100°+100°+100°+140°=540°

540°=540°
