Question

Find x
In the given figure

Answer 1

Step-by-step explanation:

if 2 sides of a triangle are equal then the angle

opposite to those sides will be equal

here

2 sides are equal so we have 2 x angles

then by angle sum property

x+x+ y=180

2x+y=180

y=180-2x=>90-x.......(dividing by 2)

let base of the triangle and the line be parallel

c=aed=180-2x

180-2x=50

130=2x

x=65
