Answer: 9</h3>
================================================
Work Shown:
a = unknown = leg #1
b = 12 = leg #2
c = 15 = hypotenuse
Plug those values into the pythagorean theorem and solve for 'a'
a^2 + b^2 = c^2
a^2 + (12)^2 = (15)^2 .... substitution
a^2 + 144 = 225
a^2 = 225 - 144 ... subtracting 144 from both sides
a^2 = 81
a = sqrt(81) .... applying square root to both sides
a = 9
Answer:

Tax = $55 * 9% = $55 * 0.09 = $4.95
Tip = $55 * 18% = $55 * 0.18 = $9.90
Total = $55 + $4.95 + $9.90 = $69.85</span><span>

the distributive property:
9(80+1)
to check the answer:
9 x 81 is 729
80 x 9 is 720
9 x 1 is 9
720+9=729
so the answer is right
the distributive property:
9(80+1)
