Step-by-step explanation:
Since the interior angles of a triangle always add up to 180°, we can use an equation to find out how many degrees the remaining angle is. We can use the letter x to represent that angle.
We also have to keep in mind that a right angle is 90°.
90+45+x=180
Now, we can start solving. First, we should combine like terms.
135+x=180
Next, we can subtract 135 from both sides to get the value of x.
135+x=180
-135 -135
x=45
So, the other angle is 45°.
Answer:
45°
