Yes it does because in order to find out if a triangle is a right triangle, you can use the Pythagorean theorem.
sqrr 2 squared + sqrr 2 squared= 2 squared
simplify this:
2+2=4
because the equation is correct, this can make a right triangle
Number of possible combinations = (4x3) ÷ 2 = 6

Answer:
0.02 ; 2%
Step-by-step explanation:
Given :
Cost of item = $480
Tax amount on item = $9.60
The sales tax rate = tax amount on item / cost of item
Sales tax rate = $9.60 / $480 = 0.02
As a percentage :
0.02 * 100% = 2%
Total coins = 10 ( 4 + 3 + 3 = 10).
The probability of picking a nickel first = 4/10 = 2/5 ( 4 nickels out of 10 total).
The probability of picking a dime second = 3/9 = 1/3 ( 3 dimes out of 9 coins left).
The probability of picking the third coin as a quarter = 3/8 ( 3 quarters out of 8 coins left).
The probability of picking all three in that order = 2/5 x 1/3 x 3/8 = 1/20
