Answer:
x = 5
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
x² + 12² = 13², so
x² + 144 = 169 ( subtract 144 from both sides )
x² = 25 ( take the square root of both sides )
x = 
= 5
multiply the 2 numbers
9 1/2 * 1 3/4 =
19/2 * 7/4 = 133/8 = 16 5/8 miles
Use Pythagoras theorem. (a^2 + b^2 = c^2)
300^2+300^2 = 180000
√180000 = 424.3
The answer is 424 foot.
Hope this helps.
The symmetric property of equality states that if two variables exist and a = b, then b = a.
So, your answer would be C (If a = b, then b = a)! :D
