I believe the measure of angle PQR would be 50 degrees. The triangle is a right triangle, meaning one angle is 90 degrees.
1) 90 + 40 = 180
90 + 40 = 130
2) 180 - 130 = 50
Therefore, Q is 50 degrees. The whole triangle is 180 degrees.
Answer: a. A point (x, y) becomes the point (y, -x) if it is rotated 270° counterclockwise. The x- and y- coordinates are interchanged and the new y-coordinate is negated. This is the same as a 90° clockwise rotation.
