Question

one angle of a parallelogram is 60°. what is the measure of angle adjacent to it

Answer 1

120°

Hope it helps..!


In parallelogram, the opposite sides are parallel and one of its property is that its opposite angles are equal,

So, when <A=60°
Opposite to it, i. e. <C=60°

Now,
It even concludes that <B=<D=x(Let)


Now

We know


Sum o the angles of a quadrilateral equals 360°


<A+<B+<C+<D=360°

OR, 60°+X+60°+X=360°

OR,X =120°

I.e <B=120°

Which is the value of adjacent angle

Answer 2

Hey mate,

We know,

Sum of adjacent angles = 180

So ,

x + 60 = 180

x = 120°

hope this helps you out!
