Question

If L||M in the following figures find the measures of x in the following with the reason

Answer 1

Answer:

it will be 50 degrees i.e,x=50 degrees

beacuase u can see 140 degrees and it lies on a straight line

straight line forms 180 degrees the other angle beside 140degrees will be

180-140=40 degrees

as you can also see the triangle as sum of angles in a triangle will be 180 degrees

we have two angle in that triangle i.e,90,40 degrees

as other angle is x

then 90+40+x=180

x=50 degrees

hope it helps.........
