NEED THE ANSWER ASAP PLEASE

Answer 1

The value of B is 112°

Explanation:

In this parallelogram, ∠A amd ∠B are adjacent angles. So when adjacent angles are add up, it will form 180°. In order to find ∠B, you have to substract 68° from 180° :

`∠a \: + \: ∠b \: = 180° \:`

Let ∠A = 68°,

`68 ° \: + \: ∠b \: = 180° \:`

`∠b \: = 180° - 68° \:`

`∠b \: = 112° \:`

Answer 2

∠ B = 112°

Explanation:

The opposite sides are parallel so figure is a parallelogram.

Consecutive angles are supplementary, thus

∠ A + ∠ B = 180°, that is

68° + ∠ B = 180° ( subtract 68° from both sides )

∠ B = 112°
