Hi! I'm supposed to calculate one of the sides in a isosceles triangle that is not right angled. Two of the sides are 9cm and I know that one of the angles is Sin(B) = 2/5.
I tried to solve it through "cutting" the triangle in half and then then try to calculate it... But i don't really know what to do after that haha
(I treid to upload an image of the problem, but apparently i didn't work)
Please help me!!
