Question

What is the value of p? A. 125° B. 45° C. 35° D. 550

Answer 1

Answer:

C- 35 °

Step-by-step explanation:

Interior angle adjacent to 90° angle = 90° (supplementary angles of a line segment).

Interior angle adjacent to 125° angle = 55° (supplementary angles of a line segment).

Sum of two interior angles of the triangle = 55+90 = 145°

∠p = 180° - 145° = 35°

Answer 2

C. 35° if you take the adjacent angle of 125° and subtract this from 180° you are left with 55°. Add this to the other 90° and you get 145°. You can then take 180°-145° to get 35°.
