Question

find the value of x​

Answer 1

Answer:

⏩Here's your answer

▶By exterior angle theorem...

▶ The exterior angle is equal to the sum of its two interior opposite angles..

⏩105+15=x

⏩120° =x

Hope it helps ✌

Answer 2

Answer:

sorry to say but don't do exterior angle sum. property it is wrong here

pls do this.

draw a perpendicular line between the parallel line dividing the 105 °angle as 90 and 15.

now in the triangle AEC

angleAEC is given as 15.

angle CAE we found to be 15

so AEC+CAE+ACE=180

15+15+ACE=180

ACE=150

now about the point c

sum of all the angles around the point is 360

so 90+150+x=360

x=120

this is the method. there are many but the answer given previously is wrong
