Question

in the following figure find x and y​

Answer 1

Answer:

Use properties sum of all angles on line is 180

Sum of all angles in a triangle is 180

a. x = 180 - (180 - (60+55)) = 60 + 55 = 115

b. x = 180 - 60 - (180 - 120) = 60

bisecting angles are equal

c.  y = 75

    x = 180 - (75 + 75) = 30

d.

  x = 180 - 70 - (180 - 120) = 50
