Question

Find measures of angles 8, 13, 11, 2 and 5.Then list one relationship that justifies the measurement

Answer 1

angle 3 = angle 8 = 75°

angle 11 = 105°

angle 11 = angle 4 + angle 13

105° = 2/3(angle 13) + angle 13

105 = 5/3 angle (13)

angle (13) = 63

2 angle (2) = angle (13)

angle (2) = 63/2

angle (2) = 31.5°

angle (5) = angle (13) = 63°

angle 8 = 75°

angle 11 = 105°

angle 13 = 63

angle 2 = 31.5

angle 5 = 63°
