#### Question No 3

An equilateral triangle is surrounded by three squares, as shown. What is the value of x?

Solution!
We have labeled the diagram to help explain this answer. PR = RS because they are sides of a square, and RS = RT because they are sides of an equilateral triangle. RQ = RT because they are also sides of a square. Therefore RQ = PR. And because RQ and PR are sides of an isosceles triangle, angle RPQ = angle RQP. Right now remember that angles of a triangle totaled equals 180Â°. And angles of a square are all 90Â° and angles of an equilateral triangle are all 60Â°. Following? Good. So all the angles at point R must equal 360Â°. Soâ€¦ Angle PRQ = 360 â€“ (90 + 90 + 60) = 120. Therefore x = (360 â€“ 120) / 2 = 30.
