Geometry HW#7-R Name: 1. The ratio of the measures of a pair of sides of a rectangle is 7:12. If the perimeter of the rectangle is 95 cm, what is the length of each side? Solve. x 9 2. 7 3 3. x 9 4 x 4. 4 x 1 x 1 36 5. Given: BD || CE Prove: AB(CE) AC(BD) E D C B Find each length. 6. 12 8 15 A 7. 8. Find SU and SV 10 x x U 9 y+1 S 3 2y V 8 R 12 9. One side of a triangle is x inches longer than another side. The ray bisecting the angle formed by these two sides divides the opposite side into 3 inch and 5 inch segments. Find the perimeter of the triangle in terms of x. 10. A student who is 5 feet 8 inches tall casts a shadow of 3 feet. How tall is a nearby tree whose shadow is 27 feet long? 11. A(1,5), B(1,1), D(10,1), E(10,-7). If CE is 10, what are the coordinates of C? A B D C E 12. Using construction tools, divide the segment into 2 pieces that are in a ratio of 2:1. 13. Construct the dilation for a scale factor of k=-2. C
