Question 2 Use the similar triangles below to determine how x2 relates to r1, Y1, and Y2. y2 y1 X1 X2 a) x2 = 21y1/Y2 b) x2 = 12/y1 %3D c) 2 = V1Y2/x1 %3D (Hint: Look at each triangle individually and determine which trigonometric function deals only with the quantities in the problem. Which trigonometric function in the small triangle only has ri and y1? Which trigonometric function in the large triangle only has r2 and y2? Note that this trigonometric function must be the same for both triangles because both triangles share the same angle 0.)
