Answer:

Step-by-step explanation:x=15??

Answer 2

Step-by-step explanation:

59. Because intersecting lines are perpendicular in this case.

60. Given, AB and CD are intersecting and OD is bisector of angle BOY

angle AOC = 3x°

and angle Aoy=90°

therefore ab and CD are intersecting line with point of intersecting as o

angle dob = angle AOC= 3 x°( vertical angles are equal)

angle dob=3x°

given, cd is a line

angle cod is a straight line and angle cod= 180°

also of is bisector

angle dob= angle doy=3x° ( since angle dob=3x°)

and, angle dob=angle doy+angle yoa+angle aoc

180°=3x°+90°+3x°

90°=6x°

X=15
