Hi there!

Since this triangle is a right triangle and a 45 degree angle is shown, we can assume that we'll need to use the 45-45-90 relationship. Using this relationship, we know that a is equal to the hypotenuse divided by the square root of 2. Since there cannot be a radical in the denominator, we need to multiply the fraction by root 2 over root 2 (or 1) and simplify.

WORK:
28/squareroot(2) x sr(2)/sr(2)
28 sr(2) / 2
a = 14 squareroot(2)

Hope this helps!! :)
If there's anything else that I can help you with, please let me know!

Answer:

The probability that the household has only cell phones and has high-speed Internet is 0.408

Step-by-step explanation:

Let A be the event that represents U.S. households has only cell phones

Let B be the event that represents U.S. households have high-speed Internet.

We are given that 51% of U.S. households has only cell phones

P(A)=0.51

We are given that 70% of the U.S. households have high-speed Internet.

P(B)=0.7

We are given that U.S. households having only cell phones, 80% have high-speed Internet. A U.S household is randomly selected.

P(B|A)=0.8

$\frac{P(A\capB)}{P(A)}=0.8\\P(A\capB)=0.8 \times P(A)\\P(A\capB)=0.8 \times 0.51\\P(A\capB)=0.408$

Hence the probability that the household has only cell phones and has high-speed Internet is 0.408
