+23245 Area of a Triangle = ½ · base· height
Using 15 for the base and 8 for the height (because they are perpendicular),
the area is: ½ · 8· 15 = 60
Now, using 17 for the base and x for the height, and we know that the area of the triangle is 60:
60 = ½ · 17· x
60 = 8.5 · x
7.06 = x (approximately) (using common fractions, the height is 120/17)
