Question

A pair of vertical angles has measures (2y + 5) and (4y) What is the value of y?

A)-5/2
B)-2/5
C)2/5
D)5/2​

Answer 1

Vertical angles are angles that are opposite each other when two lines intersect each other. And they are always equal.

==> 2y +5 = 4y

==> 4y - 2y = 5

==> 2y = 5

==>
`y = (5)/(2)`
