Answer 1

$\huge \sf {\orange {\underline {\red{\underline{Answer :-}}}}}$

$\sf\large\pink{Given⟹}$

ABCD is a parallelogram and $\tt ∠A=60°$

$\sf\large\blue{Solution⟹}$

We know that opposites angles of a parallelogram are equal.

Therefore,

${\sf{\boxed{∠A=∠C=60°}}}$

${\sf {\underline{\boxed{Formula \to ∠A+∠B=180°}}}}$

$\sf\implies 60° +∠B=180°$

$\sf\implies{ ∠B=120°}$

${\bold{\sf{\implies{\blue{ ∠B=∠D=120°}}}}}$ (opposite angles of parallelogram)
