can you explain??

anonymous · Answer

hold on did it wrong give me a min

anonymous · Answer

okay so your area of the triangle is 60, you now have to find one of the sides, so subtract whatever (8+15) is by 60 to find that one side. You should get 37. Now to check 8+15+37= is 60 so I did something wrong....
