Question

In the adjoining figure line m || line n Line l is a
transversal.
Ir. m2b = (x+20)° and
mZe = (3x+10)º find
the value of x.​

Answer 1

Answer:

Step-by-step explanation:

hey here is your answer

GIVEN ➡ (1) line m is parallel to line n

(2) l is transversal

(3) angle B = (x+15)°

(4) angle E = (2x + 15)°

solution=

line m parallel to the line n

l is transversal

angle B = angle F. (corresponding angle )

angle F = (x+15)°. -(1)

on line n

angle F + angle E = 180°. (linear pair)

(x+15)° + (2x+15)° = 180°

= 3x + 30 = 180°

= 3x = 180° - 30°

= 3x = 150°

= x = 150°/3 = 50°
