Question

Measurement of three horizontal angles about point P are: APB= 120 31’ 50”, BPC= 370 29’ 20”, and CPD= 470 36’ 30”. If the measurement of the single angle APD is 970 37’ 00”, determine the most probable values of the angles.

Answer 1

Answer:

Step-by-step explanation:

∠APD = 47°

∠APD = ∠BPC = 47° { vertically opposite angles }

∠APB + ∠APD = 180° { angles in a straight line}

∠APB + 47° = 180°

∠APB = 133° = ∠CPD { vertically opposite angles }
