According to the vertical angle theorem, vertical angles are congruent.

So, we can set up the equation 7x+1=120.

Solve. 

7x=119
x=17

Since the only answer choice with x=17 is the last choice, it is the answer.

Hope this helps!

1.64 as a mixed number in simplest form
garri49 [273]
By taking a look at 1.64, you can already tell the 1 will be the whole number in the fraction. So let's focus on .64. 0.64 is in the hundredths place value, so the denominator will be 100. The unsimplified fraction would be 1 64/100. To put this in simplest form we must divide 64 and 100. Let's start off with 2. 64/2 = 32 100/2 = 50 Let's continue until we can not divide by 2 anymore. 32/2=16 50/2 = 25 We can no longer divide by 2, howver there is not other number we can divide by both 16 and 25 evenly. The answer in simplest form is 1 16/25

The floor of a rectangular living room is 21 feet by 28 feet. What is the distance between
swat32

Answer:

35 feet.

Step-by-step explanation:

To find this, we will need to use the Pythagorean theorem to solve for the diagonal length. Call this diagonal length 'd'.

d² = 21² + 28²

d² = 1225

d² = 35.

Thus, the diagonal length is 35 feet.
