Question

Find the value of x and y ​

Answer 1

Answer:

we know that 180° is formed on a straight line

so x = 180° - 80°

= 100°

and sum of interior angle of a triangle is 180°

so y =

x + y + 30°= 180°

100° + y + 30° = 180°

130° + y = 180

y = 180° - 130°

y = 50°

hope my answer is correct and it may help you ☺
