Question

the adjacent sides of parallelogram are 4a, 3a. the angle b/w them is 60, then one of the diagonal of the parallelogram?


​

Answer 1

Explanation:

∠A=60

∘

In parallelogram Opposite angles are equal .

So ∠C=60

∘

In parallelogram adjacent sides sum up to give 180

∘

So ∠A+∠D=180

∘

∠D=180−60=120

∘

So ∠A+∠B=180

∘

∠B=180−60=120
