Since triangle ABC is a right triangle (90*), and angle ACB 45*, angle CAB must also equal 45*
Angles of triangle = 180=90+45+x
180=135+x
180-135=135-135+x
45=x

Answer:
Kk
Step-by-step explanation:
Leftside: 5x + 3x - 15 = 8x - 15
Rightside: 8x - 15
They are exactly the same.
This means x can be any real number, i.e. infinite solutions.
I'm not really sure about the property, but combining like terms and comparison are the basic tools.
