Question

four of the angles of a pentagon are equal. the fifth angle is 40°. find the angles.​

Answer 1

Answer:

each angle is of 64 degree

Step-by-step explanation:

sum of total angle of pentagon =360 degree

total angles =5

let the common no. is equals to x,

5x=360

4x+40=360

4x=360-40

4x=320

x=320/4

x=64 degree

Answer 2

125°, 125°, 125°, 125°, 40°

Step-by-step explanation:

one angle = 40

let the four equal angle = x

so, as we know sum angles of a pentagon is 540°

then, x+x+x+x+40 = 540

4x = 500

x = 125

so the angles are 125°,125°,125°,125°,40°
