- For Exercises 9 and 10, consider isosceles trapezoid RSTV with RSVT , and midpoints M, N, P, Q of the sides. Does a QN=12(RS+VT)?. b MP=12(RV+ST)?. Exercises 9, 10arrow_forwardThis sheet metal section shown in Figure 5-5 has five sets of drilled holes: A, B, C, D, and E. The holes within a set are equally spaced in the horizontal direction. Compute the horizontal distance between two consecutive holes for each set. All dimensions are in inches. A=_B=_C=_D=_E=_arrow_forwardIn ABC, M is the midpoint of AB and N is the midpoint of AC. If MN= 3x-11 and BC= 4x24, find the value of x._arrow_forward
- The center of a circle of radius 2 in. is at a distance of 10 in. from the center of a circle of radius length 3 in. To the nearest tenth of an inch, what is the approximate length of a common internal tangent? Use the hint provided in Exercise 38. HINT: use similar triangles to find OD and DP. Then apply the Pythagorean Theorem twice.arrow_forwardIn Exercises 25 and 26, give a paragraph form of proof. Provide drawings as needed. Given: Isosceles MNQ with QM=QN=s and MN=2a Prove: AMNQ=as2-a2 NOTE: sa.arrow_forwardWhat are the lengths of the following dimensions in Figure 39-11? Alldimensions are in millimeters. a.
