Question

By figure find the value of'x'
(a) 300
(b) 500
(c) 400
(d) 600
​

Answer 1

Answer:

Given:l∥m

sum of the interior angles on the same side of transversal is 180

∘

b+52

∘

=180

∘

⇒b=180

∘

−52

∘

=128

∘

And a=52

∘

∴a=52

∘

,b=128

∘

Answer 2

Step-by-step explanation:

105° + p = 180 ( sum of angles on the straight line is 180°)

p = 75°

sum of angles in the triangle is 180°

75° + 45° + x = 180°

x = 60° is the angle of x
