Since it's a right triangle you can use the Pythagorean theorem or Trig (Soh Cah Toa).
I'll just use the Pythagorean theorem : a² + b² = c²
a = 9
b = x
c = 18
9² + x² = 18²
81 + x² = 324
x² = 324 - 81
x² = 243
x = √(243)
factor 243 to find a perfect square
x = √(3*81)
x = 9√(3)<u />
The term circumscribed means to limit, to restrain, or to surround. The figure circumscribed another figure means it is outside of that figure. On the other hand, the term inscribed means to draw the figure within another. This means that it should be inside another figure.
The given descriptions above are the exact opposite of the true meaning. Hence, the answer to this item is FALSE.
So, it's just an annoying problem. Keep the tax rates in mind for each thing.
$70 of souvenirs mean the tax is 5% since it is not prepared food, lodging, or auto rentals.
$580 on prepared food means that has 7% tax because it is special.
$620 on the car has a 10% tax, as stated in the problem.
So do 70(1.05)+580(1.07)+620(1.1) to get $1376.1.0
The answer is 7 3/4 inches.
I noticed the word "train" in the problem and I knew I had to help you! :)
