Question

Q2. In given figure. Find value of a, b, c&d
If Lllm and pllq​

Answer 1

Answer:

$80 + a = 180 \: \: (co.interior \: angles) \\ a = 180 - 80 = 100 \\ 80 = b \: (interior \: angles \: are \: equa) \\ c = 80 \: (verticlly \: opposite \: angles) \\ d + 80 = 180 \: (linear \: pair) \\ d = 180 - 80 \\ d = 100$

a = 100

b = 80

c= 80

d= 100

Answer 2

Answer:

a= 100°

b=80°

d=100°

c=80°

Step-by-step explanation:

‘a’ is 100° because p and q are parallel and the inside angle make 180° so 180-80=100°

“b” is 80° because see in attachment corresponding angles

“d” is 100° because b and d are linear pair angle

“c” is 80° because c and d are linear pair

linear pair means 180° angles with a transversal

hope it helps you just say thanks and plz mark me brainliest only if you think I am capable of it

OK bye!!!!!!!!
