Question

solve the 3 problems

explanation must​

Answer 1

Explanation:

In figure I)

it's a linear pair so the sum is 180°,

so value of y is

y + 80° = 180°

y = 180-80=100°

y=100°

and , value of x = 80° because of Alternate Exterior Angle.

in figure ii)

value of x = 70° ( Vertically opposite Angle )

and value of y = 70° ( corresponding Interior Angle )

in figure iii)

value of x = 55° ( Alternate Interior Angle)

and value of y = 125°

angle y + angle x = 180°

y + 55° = 180°

y = 180° - 55° = 125°

hope this answer helps you dear....take care!
