Question

3. In the given figure, 1 || m and n is a transversal.
If mZ5 = (2x + 40)º and mZ1 = (3x + 20°, find the value
of x and mZ5.​

Answer 1

Answer:80degree

Step-by-step explanation: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
