Question

Find the value of x, if 4 || 22 3y (2y+25) 12 (x+15)​

Answer 1

Answer:

3y = x+15 ( angles on transversal)

x+15 = 2y+25 ( opposite angles)

so, 3y = 2y+25

3y - 2y = 25

y = 25

therefore, 3y = 25 × 3 = 75

and x + 15 = 75 ( from the first equation)

x = 75 -15

x = 60°

Answer 2

Answer:

if L1//L2 then :-

3y=2y+25 (angle of transverse)

=> 3y-2y =25

=> y=25°

x+15=2y+25 (opposite angle)

=>. x+15=50+25

=>. x=75-15

=60°
