The true statement she could write is angle PRQ measures 75 degrees
From the diagram shown, we are told that line n is parallel to m. For Charlotte to prove that the sum of the measures of interior angles of triangle PQR is equal to 180°, then he needs to get two other interior angles of the triangle PQR.
To get <PQR, she needs to compare the angle 35 degrees to <PQR using the alternate angle theorem and 75 degrees to <PRQ using the alternate angle theorem. Since alternate angles are equal, then she can conclude that:
<PQR = 35 degrees and <PRQ = 75degrees
Hence the true statement she could write is angle PRQ measures 75 degrees
