Question

Quadrilateral QRST is a square. If the measure of angle RQS is 5x – 15. Find the value of x.

Answer 1

x=12 because the angle is half of 90 since the diagonals of a square bisect the four angles into two halves. you set the equation equal to 45 and solve for x

Answer 2

angle of RQS = 45 degrees so

5X-15 = 45

5x=60

x = 12
