Let's find the value of x

Since the sum of internal angles of a triangle is 180°

therefore,

\hookrightarrow \: (2x - 2) \degree + (x + 5) \degree + 90 \degree = 180 \degree

\hookrightarrow \: 2x - 2 \degree + x + 5\degree  = 180\degree - 90\degree

\hookrightarrow \: 3x + 3\degree = 90\degree

\hookrightarrow \: 3(x + 1) = 3(30)

\hookrightarrow \: x + 1\degree = 30\degree

\hookrightarrow \: x = 29\degree

The length of which line segment is equal to the exact value of the sine if theta?
Ainat [17]
<h3>Answer: Option 2. Segment TS</h3>

====================================================

Explanation:

Recall that the sine of an angle is equal to the ratio of opposite over hypotenuse.

In other words,

sin(angle) = opposite/hypotenuse

With respect to reference angle theta, the side TS is opposite this angle. It is the leg furthest from the angle. The hypotenuse is the longest side segment TO. The hypotenuse is always opposite the 90 degree angle.

For a unit circle, the radius is 1, so segment TO is 1 unit long.

Therefore,

sin(angle) = opposite/hypotenuse

sin(theta) = TS/TO

sin(theta) = TS/1

sin(theta) = TS

? is in the picture plssssssssssss
Nimfa-mama [501]

Answer:

Yes, the table is proportional.

Step-by-step explanation:

The way I check to make sure if a table is proportional, I subtract.

I did this: 122 - 104, 104 - 86, 86 - 68, 68 -50, and 50 - 32.

If all of them equal the same number, then the table is proportional.

If not, then the table is not proportional.

Each equation equals 18.

Therefore, the table is proportional.

A number is selected at random from the set {1,2,3,…,1000}. What is the probability that it is divisible by 19?
11111nata11111 [884]

Answer:

the probability is %5.2

Step-by-step explanation:

To know the probability that it is a multiple of 19 we have to know the number of multiples that 19 has between 1 and 1000. And that amount divide it by 1000. Finally we multiply it by 100 and we will have the percentage.

To know how many multiples there are from 1 to 1000 we have to make 1000 divided by 19 and the number that we get the decimals.

1000/19 = 52.63

there are 52 multiples

100*52/1000 = 5.2

the probability is %5.2

Answer:

68ft

Step-by-step explanation:

So first I separated the figure into two rectangles and found the area of each. The the first figure's area was 8ft and the next was 60ft. Therefore, 60 + 8 = 68ft.

Hope this helps!
