We have to find the height of the triangle to find its area. The altitude to the base of an isosceles triangle is also the median, meaning the altitude forms a 6-8-10 right triangle, so the length of the height is 8, and therefore the area is 0.5 * 8 * 12 = 48.
First you should find the discount so you can say: 10/100 = ?/82 so ? is your discount and ? is equal to: ? = 82*10/100 = 8.2 so your discount is $8.2 and your sale price will be: $82 - $8.2 = $73.8 :))) I hope this is helpful have a nice day
