Are the angles supplementary if m∠A=98° and m∠B=88° ?

Question

(1 point)

A. No, they do not add up to 90°

B. No, they are not adjacent.

C. No, they do not add up to 180°

D. Yes, they are a supplementary pair.

Answer 1

To determine if angles A and B are supplementary, we need to check if their measures add up to 180°.

Given:

• m∠A = 98°
• m∠B = 88°

Now, let's add the measures of the angles: m∠A + m∠B = 98° + 88° = 186°

Since 186° does not equal 180°, the angles are not supplementary.

The correct answer is:

C. No, they do not add up to 180°.
