Answer:
45 degrees
Step-by-step explanation:
The interior angles of a triangle add to 180 degrees.
<ABC + <BCA + <CBA = 180
We know <ABC is 90 degrees, and <BCA is 45, so we can substitute them in.
90+45+<CBA=180
Combine like terms by adding 90 and 45
135+<CBA=180
Subtract 130 on both sides to get the variable by itself
<CBA=45
Given 2 angle : 45 and 90 (right angle)
==> 180-45-90 = 45
