Question

Look at the intersecting lines below.
What is the value of a?

Answer 1

a = 22°

Explanation:

Since vertical angles are always congruent we know that 46° = 2a + 2°, therefor...

46° = 2a + 2°

2a = 46° - 2°

2a = 44°

a = 44° / 2

a = 22°

Answer 2

a=22

Explanation:

2a+2=46

2a=46-2

2a=44

a=44÷2

a=22
