Question

Q.44 In the given figure x =

a. 80°
b. 60°
C. 50°
d. None of these​

Answer 1

Answer:

50°

Step-by-step explanation:

y = 80° (vertically opposite angle)

y + x + x = 180° (straight angle)

80 + 2x = 180°

2x = 180 - 80

2x = 100

x = 100/2

x = 50.

Answer 2

Answer:

option C

50 degree

as the total sum of angles will be 360 degree

we will subtract 160 from 360 because adjacent angle of 80 degree is equal to it that is 80 degree.

after adding 80+80 we get 160

then 360-160=200

there are four angles of x

so 200/4=50 degree
