Question

in the figure,find the value of x​

Answer 1

x = 80

given that the two sides are parallel..

so x = 80 ..

= 80+80=160

=another side is 180 - 160 =20

we know that the sum of 3 sides of a triangle = 180

80 + 80 + 20 = 180

Answer 2

Answer:

x=50

Step-by-step explanation:

we know it is an isosceles triangle in which opposite side and opposite angles are equal

then

x+x+80=180

2x+80=180

2x=180-80

2x=100

x=50
