Answer 1

Step-by-step explanation:

1)

Since. line p and q are parallel also l and m are parallel then

$a + 60 \: = 180 \\ \: \: (same \: \: side \: \: of \: \: parallel \: \: line \: p \: and \: q) \\ = > a = 180 - 60 \\ = > a = 120$

$a = d \: = 120 \: \\ (alternate \: \: exterior \: angle)$

$c + d = 180 \\ (linear \: \: pair \: of \: line \ \: \: m) \\ = > c + 120 = 180 \\ = > c = 180 - 120 \\ = > c = 60$

$c = b = 60 \\ (vertically \: \: \: opposite \: angle)$

HENCE a =d = 120°

b= c = 60°

Similarly in que. 2nd try to solve.
