Find angle 1
149 degrees
118 degrees
69 degrees
59 degrees

∠A = 118°

Step-by-step explanation:

By using the property of parallelogram, diagonals bisect each other,

So ∠D = 31° + 31° = 62°

Another property of parallelogram says that,

consecutive angles are supplementary, that is ∠A and ∠D add up to 180 degrees.

Now we have the angle D as 62°, to find A, we can write as,

∠A + ∠D = 180°

∠A + 62° = 180°

It was rewritten to get ∠A as,

∠A = 180° - 62° = 118°

the answer is the third / last answer
