Question

guyzzzz I posted 2 to 3 questions wid pics. but noooooo response wid step by step soi request you atleast can u give diz answers ,, if possible please check my previous pics.and answers me Plzzzzzzzzz , thanks atons to u allll.​​

Answer 1

we are well aware of the fact linear pair = 180°

Angle A = 180° - 70° [Linear pair.]

= 110°

Angle D = 180°-80° [linear pair]

= 100°

Angle C = 180° - 100°[linear pair]

= 80°

°•° Both the lines are parallel

So,

by applying sum of A.I.A[alternate interior angle] is equal to 180°

assume that unknown angle be x

Angle x + 70° = 180°

x = 110°

Angle B = 180-110 [linear pair]

=70°

Answer 2

hey mate it's normal to get no response. sometimes users may find your question too difficult so they leave without answering.

however here's the answer of this question

angle b=70°..alternate angles

angle c=80°...linear pair

angle d=100°...linear pair

angle a =110°...linear pair

hope this helps you.
