Answer 1

Answer:

\sf { \underline{SOLUTION}}

SOLUTION

GIVEN

∠A and ∠B are two adjacent angles of a parallelogram.

∠A = 70°

TO DETERMINE

The value of ∠B

CONCEPT TO BE IMPLEMENTED

Adjacent Angles in a parallelogram are always supplementary

EVALUATION

We are aware of the property that Adjacent Angles in a parallelogram are always supplementary

That is, sum of the adjacent angles in a parallelogram is 180°

Now it is given that

∠A = 70°

Since ∠A and ∠B are two adjacent angles of the parallelogram

∴ ∠B = ( 180° - 70°) = 110°

FINAL ANSWER

∠B = 110°
