Question 715071: An isosceles triangle has a base of 10 and legs of 13. Another isosceles triangle has legs of length 13, but has a different base. The triangles have the same area. What is the length of the base of the second triangle?
I found the area of the first triangle by splitting it in half and using the Pythagoreum theorem to find the height.
5^2+h^2=13^2
25+h^2=169
H^2=144
H=12
1/2(10)(12)=60

Question 716018: Dear Edwin McCravy,

Hopefully you are very fine. Your previous solution worked very well. Now I am asking for another solution.

If I have the length of the base of a triagle, an obtuse angle adjacent to the base and the difference between the other two sides of the traingle, how can I draw the triangle.

Thanks for your kind perusal and I would be grateful if you please provide me with the solution.

Best regards.
