an isocoles triangle that has two sides measuring 10 and one side measuring 12 what would be the angles with two of them being equal?
--------------------
You can use the Cosine Law:
12%5E2+=+10%5E2+%2B+10%5E2+-+2%2A10%2A10%2Acos%28A%29
and solve for the cosine.
-----------------
Or, use sin(A/2) = 6/10
A/2 =~ 36.87 degs
A = 73.74 degs
----------------
Angles B & C = (180 - A)/2
