Answer 1

Answer:

Your answers are given below.

Step-by-step explanation:

So, before we start to find A and B, we first have to find the angles that supplementary with ∠A and ∠B.

Let the angle supplement with ∠A be x

65° + x = 180° (Adjacent angles are supplementary)

x = 180° - 65°

x = 115°

Let the angle supplement with ∠B be y

105° + y = 180° (Adjacent angles are supplementary)

y = 180° - 105°

y = 75°

Now, to find ∠A, we have:

115° + ∠A = 180° (Supplementary angles)

∠A = 180° - 115°

∠A = 65°

And to find ∠B, we have:

105° + ∠B = 180°

∠B = 180° - 105°

∠B = 75°

Hope it helps you!
