Question

In figure, lines AB,CD and EF intersect at O. Find the measures of

Answer 1

Answer:

we know that the sum of a straight line is 180 °

so, 40°+35°+o = 180°

then value of o=180°-75°

=105°

According to vertically opposite angle method value of opposite o is equal to value of o

Hence, value of angle cof is 105°
