1) name a pair of complementary angles. 2)name a pair of vertical angles. 3)name a pair of supplementary angles.

1)m<AOB,m<BOC

2)m<EOD,m<AOB

3)m<AOE,m<EOD

Step-by-step explanation:

Complementary Angles-either of two angles whose sum is 90°.

Vertical Angles-each of the pairs of opposite angles made by two intersecting lines.

Supplementary Angles-either of two angles whose sum is 180°.

step-by-step explanation:

we need to solve for 'x' the following equation:  

we have that:

⇒

⇒ ⇒

factorizing, we get that:

  ⇒

then, the solutions are: or
