Question No 10

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

Select the correct answer

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.
