PQR is most likely a triangle

**Answer:**

All triangles add up to 180 degrees

right angles are 90 degrees

we add 41 and 90 to find how many degrees are already there

41 + 90 = 131

we need 180 degrees so we see how many degrees are left

180 - 131 = 49

49 degrees are left so 49 is the answer because 49 finishes the triangle
