Question

in the figure line a parallel line b and line c is the transversal ∆abc=3z° and ∆bcd=75° the value of z is​

Answer 1

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

$\huge\underline\mathbb\red{ANSWER⤵⤵:-}$

CORRECT ANSWER IS:-

a = 52° and b = 128°

we know that ∆bcd = 75°

➡3z = 75°

= z = 75°/ 3

$= \underline{z = 25°}$
