PLEASE HELP BRO WILL GIVE BRAINLIA student writes an incorrect step while checking if the sum of the measures of the two remote interior angles of triangle ABC below is equal to the measure of the exterior angle. A triangle ABC is shown. The base of the triangle extends into a straight line. The angle formed between this straight line and the edge of the triangle is marked as p. The angle adjacent to p is marked as o, and the other two angles inside the triangle are marked as m and n. Step 1: mm + mn + mo = 180 degrees (sum of angles of a triangle)Step 2: mp + mo = 180 degrees (adjacent supplementary angles)Step 3: Therefore, mm + mn + mo = mn + mpStep 4: So, mm + mn = mpIn which step did the student first make a mistake and how can it be corrected? (4 points) Step 2; it should be mo mp = 90 degrees (complementary angles) Step 1; it should be mm + mn + mo = 90 degrees (adjacent angles) Step 1; it should be mm + mn + mo = 90 degrees (corresponding angles) Step 3; it should be mm + mn + mo = mo + mp yo can anyone help me solve this rq i need it for tomorrow Read each of the sentences that describe a phase of mitosis.
