Question

In the figure, If line m | line n., then the value of x is
(a) x= 130°
(c) x= 50°
(b) x= 550
(d) x = 65°​

Answer 1

Answer:

$2x + 50 = 180 \\ 2x = 130 \\ x = \frac{130}{2 } \\ x = 65$

d) x = 65°

Step-by-step explanation:

Hope it helps..

Answer 2

Answer:

(d) x = 65°

do you want explanation???

On the left side of 2x, I named that angle as b

so angle b is equal to 50° (alternate angles are congruent)

so,

50° + 2x = 180° ( angles in linear pair ).

2x = 180 – 50

x = 130/2

x = 65°
