Answer: refresh
Step-by-step explanation:
A right triangle has three sides: the two sides that share a vertex are known as the legs, and the other side is known as the hypotenuse. The legs are known as a and b, while the hypotenuse is c.
The Pythagorean Theorem states the a^2 + b^2 = c^2. If we plug the numbers into this equation, we will find the length of the hypotenuse.
39^2 + 80^2 = c^2
1521 + 6400 = c^2
7921 = c^2
We have c squared now, but we want to know how much c is equal to. The square root of c^2 will be our answer.
89 = c
The length of the hypotenuse of a right triangle with legs that measure 39 and 80 inches is 89 inches.
Answer:
27 and 36
Step-by-step explanation:
x + (x - 9) = 63
2x - 9 = 63
add 9 to both sides
2x = 72
Divide both sides by2
x = 36
x - 9 = 36 - 9
x - 9 = 27
Answer:
252 is the least common multiple
Step-by-step explanation:
For there to be 1 car, we consider two possible outcomes:
The first door opened has a car or the second door opened has a car.
P(1 car) = 2/6 x 4/5 + 4/6 x 2/5
P(1 car) = 8/15
For there to be no car in either door
P(no car) = 4/6 x 3/5
P(no car) = 2/5
Probability of at least one car is the sum of the probability of one car and probability of two cars:
P(2 cars) = 2/6 x 1/5
= 1/15
P(1 car) + P(2 cars) = 8/15 + 1/15
= 3/5
