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°.

45°
