Need help with 61. Show steps please.
skelet666 [1.2K]
Just do 3x+5+2x=90 And solve for x.

So, 5x+5=90
5x=85
x=85/5 = 17

now you know the value of x, so you can calculate the angles.

Btw the total angle of a triangle is 180, and since this is a right angle triangle, you know that the two angles added together needs to equal 90.
