PLEASE HELP Charlotte is writing statements to prove that the sum of the measures of interior angles of triangle PQR is equal to 180°. Line m is parallel to line n. Which is a true statement she could write?
A) Angle PRQ measures 35°.
B) Angle PRQ measures 75°.
C) Angle PQR measures 70°.
D) Angle PRQ measures 70°.

Option B is true.

Step-by-step explanation:

Since two line m and line n are parallel and PR is a transverse,

angle PRQ and  angle RPN will be interior alternate angles.

Therefore, ∠PRQ = 75°

Option A. Angle PRQ measures 35°

False

Option B. Angle PRQ measures 75°

True

Option C. Angle PQR measures 70°.

In triangle PQR,

m∠PQR + m∠PRQ + m∠QPR = 180°

m∠PQR + 75° + 70° = 180°

m∠PQR = 180-145 = 35°

False

Option D. Angle PRQ measures 70°.

False

konichiwa~! my name is zalgo and i am here to answer your anime-related question today. more than likely, kirishima would kill izuku, marry mino and kiss momo. all of this would be my opinion by the way. (and i am also a weeb lol)
