Question

David drew triangle PQR as shown.

If QPR measures 135, which statement is true for PQR and PRQ?
Please Help!

Answer 1

The correct answer is that the other two angles must add up to 45 degrees.

Explanation:

This is because all 3 angles in a triangle will add up to 180 total degrees. If we subtract 135 from 180, we get the remaining 45 degrees.

Answer 2

The sum of the other two angles must add on to
`45^(\circ)`

Explanation:

It is given that PQR is a triangle and the measure of the
`{\angle}QPR=135^(\circ)`.

Now, we know that the sum of all the angles of the triangle must be equal to 180°, and it is given that the measure of the
`{\angle}QPR=135^(\circ)`, therefore, the sum of the other two angles must add on to
`45^(\circ)` in order to fulfill the condition that the sum of the triangle is 180°.
