- Circles O, P, and Q are tangent as shown at points X, Y, and Z. Being as specific as possible, explain what type of triangle PQO is if: a OX=2,PY=3,QZ=1 b OX=2,PY=3,QZ=2arrow_forwardDoes it follow from Exercise 30 that ADE is also congruent to CBE? What can you conclude regarding AE and CE in the drawing? What can you conclude regarding DEandBE?arrow_forwardGiven: Hole centerlines EFGH and MPKL. Determine the values of 1 through 15 for these values of 16 .arrow_forward
- Given that CF is a tangent to the circle shown: a)CF=6,AC=12,BC=?b)AG=3,BE=10,BG=4,DG=?c)AC=12,BC=4,DC=3,CE=?d)AG=8,GD=5,BG=10,GE=?e)CF=6,AB=5,BC=?f)EG=4,BC=3,CD=ED,ED=?g)AC=30,BC=5,ED=12,CD=?h)AC=9,BC=5,ED=12,CD=?i)ED=8,DC=4,FC=?j)FC=6,ED=9,CD=?arrow_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_forwardThe 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_forward
- Given: Hole centrelines ABCD and EFGH . Determine the values of 1 through 22 for these given values of 23,24 , and 25. a. 23=97,24=34,and25=102 b. 23=11223,24=2753,and25=9518arrow_forwardProve by the indirect method: Given: Scalene XYZ in which ZW bisects XZY point W lies on XY. Prove: ZW is not perpendicular to XYarrow_forwardIn Exercises 44 to 47, prove the stated theorem. If two secant segments are drawn to a circle from an external point, then the products of the length of each secant with the length of its external segment are equal. See Figure 6.51 on page 294.arrow_forward
