Answer:
37 degrees
Step-by-step explanation:
The first thing you have to do is realize all angles in a triangle have to add up to 180 degrees.
So you would make you equation
[tex]2x + 15 + 5x - 2 + 90 = 180[/tex]
Then you put all your constants on one side and the X's on the other. So you get
[tex]7x = 77[/tex]
Then your x =11
To find that angle
[tex]2x + 15[/tex]
You just plug in 11
[tex]2(11) + 15[/tex]
=37
