Quadrilateral QRST is a square. If the measure of angle RQS is 5x – 15. Find the value of x.
2 answers:
angle of RQS = 45 degrees so
5X-15 = 45
5x=60
x = 12
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
