  1. 1. Geometry is everywhere ... you just have to look ... Sinai Penninsula and Dead Sea from Space Shuttle Columbia, March 2002 (NASA)
  2. 2. Mental Math Given the following information, name the 7. If you bought a bottle of letter of the angle which corresponds to it : pop for $1.69, what change a = 12, b = 13 , c = 5 would you get back from a $5, starting with pennies. 1. Tan ? = 12/5 A 1p, 1n, 1q, 1L, 1T 2. Sin ? =5/13 C Using the 15 minute rule, how 3. Cos ? = 5/13 A many hours will Suk be paid for, given the following: 4. Cos ? = 12/13 C 8. 12:00 – 15:23 3 h 15 m 5. Tan ? = 5/12 C 9. 3:45 – 8:30 4 h 45 m 6. What are 3 different 45 p or 10. What is 37.5% of 40? 15 ways to make $0.45? 1q, 2d or 4d, 1n, etc.
  3. 3. The length of the shadow cast by a tree is 6.8 m. At the same time the length of the shadow cast by a 40 cm plant is 65 cm. How tall is the tree?
  4. 4. The length of a shadow cast by a telephone pole is 18 m. At the same time of day, then length of a shadow cast by a 80 cm post is 180 cm. How tall is the pole?
