Step-by-step explanation:

Answer 2

Answer

Given:- exterior angle = 120⁰

             interior angles = 5:1

Find :- interior opposite angle

= let be the number x

= 5x + 1x = 120⁰ ( because the exterior is equal to 2 interior angles)

= 6x = 120⁰

=x = 120/6

= x = 20⁰

= 5 X x = 5 X 20

= 100⁰

= 1 X x = 1 X 20

= 20⁰

NOW THE ANOTHER ANGLE WILL BE 60⁰

LET BE ANOTHER INTERIOR BE x

because 20⁰ + 100⁰ + x = 180⁰( ASP)

= 120⁰ - x = 180⁰

= x = 60⁰
