Question

Find the value of (x), when a penatagon has

the following interior angles, 90 degrees, 125
degress, 2x degrees, 125 degrees and 2x
degrees

Answer 1

x=50

Explanation:

the sum of interior angles in a pentagon is 540.

So, 90+125+2x+125+2x=540 90+125+125=340

340+4x=540 540-340= 200

4x=200 200/4=50

x=50
