Question

in the given figure, l || m and n is a transversaltranserval.
if m angle 5=(2x+40)° and m angle 1=(3x+20)°, find the value of x and m angle 5​

Answer 1

Step-by-step explanation:

Angle 5 and Angle 1 are corressponding angles.

They are equal.

So, 2x+40 = 3x +20

x=20

and angle 5 = 2×20 +40 = 80⁰

Answer 2

Answer:

as, l//m and n is transversal

angle 5 = angle 1 ( corresponding angles)

( 2x+ 40)=(3x+20)

= 2x+40= 3x+20

= 2x-3x = 20-40

= -x = -20

= x=20

angle 5 = 2(20)+ 40

= 40 + 40

= 80
