Question

find the value of x in the figure if l // m​

Answer 1

ANSWER

Sum of co- interior angles = 180

x+2x=180

3x =180

x=180/3

x=60°

Answer 2

Answer:

x = 60°

Step-by-step explanation:

Follow the picture along with explanation for better understanding

∠B = 2x (Alternate interior)

∠B + x = 180° (Linear Pair)

$= 2x + x = 180$

$\frac{3x}{3} = \frac{180}{3}$

$x = 60$
