- If AC is a diameter of O, find the area of the shaded triangle. Exercise 17arrow_forwardThe center of a circle of radius 2 inches is at a distance of 10 inches from the center of a circle of radius length 3 inches. 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_forwardA tangent ET is constructed to circle Q from external point E. Which angle and which side of triangle QTE are largest? Which angle and which side are smallest?arrow_forward
- Suppose a circle of radius r is inscribed in a rhombus, each of whose sides has length s. Find an expression for the area of the rhombus in terms of r and s.arrow_forwardGiven: Equiangular RST Prove: RV bisects SRT RVS is a rightarrow_forwardaBecause point Q is their common center, these circles are known as _ circles. bIf RQ=3 and QV=5, find the length of chord TV which is also a tangent to the inner circle.arrow_forward
- In O with diameter AC, OC=5 and AB=6. If M is the midpoint of BC, find AM.arrow_forwardGiven: Regular pentagon JKLMN not shown with diagonals LNandKN. Find: mLNKarrow_forwardA circle is inscribed in an isosceles triangle with legs of length 10 in. and a base of length 12 in. Find the length of the radius of the inscribed circle.arrow_forward
- The center of a circle of radius 3 inches is at a distance of 20 inches from the center of a circle of radius 9 inches. What is the exact length of common internal tangent AB? HINT: Use similar triangles to find OD and DP. Then apply the Pythagorean Theorem twice.arrow_forwardFind the exact perimeter and area of the segment shown, given that mO=600 and OA=12 in.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
