Trigonometry has many applications in the real world. One particular area in which it can be used is in architecture. If you were an architect, describe a specific situation in which you could use right triangle trigonometry to help you design a new hospital. Give a specific example and explain how right triangle trigonometry co

A ranger in fire tower A spots a fire at a direction of 295 degrees. A ranger in fire tower B, located 45 miles at a direction of 45 degrees from tower A, spots the same fire at direction of 255 degrees. How far from tower A is the fire? From tower B?

Hello!
I was in the hospital during my spring break, and I am in desperate need of "flash cards" covering surface area as well as volume for typical polygons. Pythagorean theorem, cylinders, cones, etc.
Please help!
Best regards,
