The triangle in the pic is an isosceles triangle.
As it is an isosceles triangle , it's two sides will be equal .



Also, both the base angles will be equal.



According to angle sum property of a triangle , sum of measure of all the angles of a triangle is equal to 180°. So,



Let x be your first alloy
2/5x+7/10(30-x)=1/2(30)
4x+210-7x=150
3x=60
x=20
So, you need 20 lbs of the first alloy, and 10 parts of the second to make 30 lbs of half iron and half silver alloy!
