Question

If the m<7 = 115 degrees, find the measure of <2

Answer 1

If they are complementary angles, then we know that they have a sum of 180°.

∠7=115°
∠7+∠2=180°
plug in the data we know
115+∠2=180
subtract 115 from both sides
65°=∠2

Answer=65°

Answer 2

Answer:

The measure of $\angle 2$ is 115°.

Step-by-step explanation:

Now, assuming those angles are supplementary, then

$m\angle 7+ m \angle 2=180\°$

Beacuse, sumplementary angles sum 180\°, due to their position on a straight angle.

We know by given that $m \angle 7 =115\°$, replacing this value, we have

$115\°+ m\angle 2= 180\°\\m \angle 2=180\° - 115\°\\m \angle 2= 65\°$

Therefore, the measure of $\angle 2$ is 115°.
