If ∠X = 90^o - ∠Y , then ∠X and ∠Y are _________ angles.

A line which intersects two or more lines at distinct points is called a 

If angles (2x - 10 )^o and (x - 5 )^o are complementary angles , the value of x is

If two lines intersect each other, the vertically opposite angles are 

In figure if ∠A = (3x + 2)^o ,∠ B = (x - 3)^o and ∠ACD = 127^o , then x =

If a ray stands on a line,then the sum of two adjacent angles so formed is

An angle is 18^o less than its complementary angles, the measure of this angle is

An angle is equal to 5 times its complement.The measure of the angle is

If the complement of a angle is equal to the supplement of 4 times the angle.Then the measure of the angle is

In figure if l || m and l is a transversal , determine x.
