Question

in figure line l parallel to m and line l is transversal find value (75-2x) (3x+25)

A) 10
B) 20
C) 30
D) 40

please answer with Step by step explanation Thank you :)​

Answer 1

Step-by-step explanation:

angel (75-2x)° = angel (3x+25)°

[because the alternate exterior angels are equal]

75-2x = 3x+25

-2x-3x = 25-75

-5x = -50

5x = 50

x = 50/5

x = 10

so, angel (75-2x) = 75-2×10

= 75-20

= 55°

and angel (3x+25) = 3×10+25

=30+25

=55°

Hence, angel (75-2x) = angle (3x25)

55° = 55°
