Question

if line l is parallel to line m . find x

​

Answer 1

Answer:

Given:

L II m , A is transversal line passing through L and m

Solution:

Since A is transversal , angle DBC = angle DAL¹

Therefore angle DBC = 65°

Consider ∆DBC:

Total angle is the Triangle=180°

65°+40°+BDC=180

105°+BDC=180

BDC=180-105=65°

Consider straight line A

Angle in a straight line=180°

Therefore x+65=180

=>x=180-65

=>x=105°

Answer 2

Answer:

105°

Step-by-step explanation:

$angle A = angle B$

$therefore \\angle B = 65$

we know that,

$x = B + C\\x = 65 + 40 \\x = 105$
