Question

two lines ab and cd intersect at o such that boc+acd=290 degree find all the four angles

Answer 1

Answer:

Step-by-step explanation:

angle BOC+ANGLE AOD=280

LET BOC AND AOD =x

angle x+angle x =280

2x=280

x=140

for angle BOD,

180-140=40(ADJACENT ANGLES)

COA=BOD

=40(VERTICALLY OPPOSITE ANGLE)
