Answer plz : ) i don’t even know what this is

115°

Step-by-step explanation:

∠8 and ∠ 5 are vertically opposite angles and congruent, hence

∠5 = ∠8 = 115°

D. 115 deg

Step-by-step explanation:

Look at just the two lines that intersect forming angles 5, 6, 7, and 8.

When two lines intersect at a point, they form 4 angles. Each pair of angles that are opposite each other, such as the pair of angles 5 and 8 and the pair of angles 6 and 7, is called vertical angles. Angles 5 and 8 are vertical angles. Angles 6 and 7 are vertical angles.

Theorem:

Vertical angles are congruent.

If two angles are vertical angles, they are congruent. This means that their measures are equal. Angles 5 and 8 are vertical angles and congruent. Their measures are equal. Since the measure of angle 8 is 115 deg, then the measure of angle 5 is also 115 deg.

Choice D: 115 deg

hi,

i'm 75% sure the answer is 1,1 to both lines.

have a great day

the answer is 99.
