Question

bhaiya pls answer this question​

Answer 1

Answer:

1)

In the 1st question -

x = (180-50). ------------{linear pair}

x = 130°

y = x = 130°. -------------{alternative interior angles}

OR

y = 130° ---------{Vertical opposite angles}

2)

in the 2nd question -

x = Angle APQ = 50°. ------------{Alternative interior angles}

x = 50°

we know that,

y + x = Angle PRD ------------{exterior angle property}

y = 127 - 50

y = 77°
