Question 308812: 10. Solve for x and y. There are 2 triangles, the one on the left has 25 at the top, 5x in bottom left hand corner. The second triangle has 4y at the top, 100 degrees in left hand corner, and 16 in the right hand corner.
24. A cylindrical storage tank has a diameter of 70 feet and is 95 feet high, how many cubic feet can it store?
32. In the triangle, what is tan B? The hyp is 10, adj side is 4, opposite side 8.
33. If XY=8, find ZY. There's a triangle with 8 on side XY (very left side), the base is X, and the side across the 90 degree angle is blank. There's also a 30 degree angle which is Z.
34. The angle of elevation from a ship to the top of a rocky cliff is 15 degrees. If the ship is 110 meters from the base of the cliff, how high is the cliff?

Question 309694: Regarding a triangle which has a 90 degree angle...is there a simple formula to take a given diagonal dimension (hypotenuse) and a constant vertical / horizontal dimension relationship (16:9), and determine the vertical / horizontal dimensions from a given diagonal dimension. For example, if I use the basic 16 horizontal dimension, and the basic 9 vertical dimension, the hypotenuse will be 18.357...
Hence, working in reverse, what would be the formula I could use to plug in a given hypotenuse (20, 22, 23, 24, 25, 50, 100, etc. and using the non variable 16:9 ratio, come up with the vertical and horizontal dimensions?
I hope I did OK with making my question clear.
Thanks.

Question 310356: The email given earlier is not correct :( I am sorry here is the right one.
You are given an exteded ratio that compares the lengths of the sides of the triangle. find the lengths of all unknown sides.
DE:EF:DF is 4:5:6 DE=16 EF=y DF=y+4
I tried 4(16)+ 5(y) + 6(y+4) but the answer in the back of the book isn't the same answer I get. I have had no instruction in Geometry since the beginning of April as I haven't been going to regular school. I have been in a homebound program and never got anything with Geometry until now. I hope you can help me. I have a final to take and I haven't done anything in any chapters past 4.
