Answer:

11

Explanation:

area = (side a + side b)/2 times height

side a = (2 times (area ÷ height)) - side b

side a = (2 times (54+6)) - 7

side a = (2 times (9)) - 7

side a = 18 - 7

side a = 11

to get the hypotenuse of the triangle

11 - 7 = 4

base of the triangle is 2 (2 on either side)

pythagorean theorem

a squared + b squared = c squared

4 + 36 = 40

to get c or the hypotenuse

take the square root of 40
