solution of an oblique triangle with two sides equal.

Question

where the included angle is 95 and two sides are 30.

Answer 1

The other two angles of this isosceles triangle are (180-95)/2=42.5 degrees. To find the length of the other side we use the fact that the angle bisector in an isosceles triangle bisects the opposite side. The hypotenuse is 30 and the bisected angle is 95/2=47.5. The length of the third side is 30*2sin47.5=44.24 approx.
