Find the median to the base of an isosceles triangle if the length of its base is 15 in and its area is 75 in2

See the attached figure to understand the problem

we know that
the median to the base is the segment BD
the base AC is 15 in
Area=75 in²
Area=AC*BD/2---------> BD=(Area*2)/AC---------> BD=(75*2)/15
BD=10 in

the answer is BD=10 in

Answer for 2: his profit would be $2.88 explanation: you have to first multiply 72 and 0.12 together to get $8.64 once you do that you know how much money the shopkeeper made from selling the candy bars individually. so you have to do 8.64-5.76=2.88 hope that ; )answer for 3: yeah i’m sorry i have no idea what number 3 is. i’m sorry i couldn’t with that.
