Find the measure of &lt;7
Montano1993 [528]
Hey there! :D

Vertical angles are congruent, they have the same measure. 

So, <7 and <5 are vertical angles. They share the same vertex, and if you were to draw a straight line between them, it would connect and bisect them both equally. 

<5= 45, so <7= 45. 

I hope this helps!
