Question

The four exterior angles of a pentagon are 80⁰, 65⁰, 70⁰, 75⁰ then its fifth angle measure is

Answer 1

Step-by-step explanation:

80°+65°+70°+75°=290°

so, the fifth angle of pentagon is 290°

Answer 2

Answer:

the sum of exterior angles in a polygon is 360°

so the fifth angle measure will be

= 360 - (80+65+75+70)

= 360° - 290°

= 70°
