Question 308413: I have a triangle, it is an isoceles (I think i spelled that wrong). I know it is isoceles because it has a base then, the two sides are marked congruent. I have the degree measure of one angle, its 70 degrees. So, i found out the other degree angles are 70, and 30. It gives me the base length, 10. I need to find the area. I know to find the area, I need to find the height. (A= 1/2 bh) That's where I got stuck. How do I do this problem? Thank you.

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.
