Hello,

No a triangle with these angles are not unique. This is because every triangle is supposed to have 180 degrees, just like this one.

Have a great day!

It’s C since it is open and x is less than 2. We can plug in any number on the number line to see if this makes sense.

For this, you have to understand the ratios of a 30,60,90 triangle. The ratio(in order) is x, x(sqrt 3), 2x (following the 30,60,90 pattern y'know). Well, we know the length of the hypotenuse, 4.2, so let's use ratios to figure the other sides out. The ratio of AC is x and the ratio of AB is 2x, so 2x/2=x=2.1. One side down. BC has a ratio of x(sqrt 3). We already know x so we can substitute it in. We get 2.1(sqrt 3). To calculate the area, use the formula 1/2(bh). Inputting the values in, we get 1/2(2.1*(2.1(sqrt 3)). This can be calculated to around 3.82. To calculate the perimeter, take the sum of the sides. By adding the sides together, we get about 9.98. Hope you can now understand how to do these kinds of questions.

The segments shown below could form a triangle.

False because 7+8=15. The two sides need to add up to more then the hypotenuse

Find the mean and median of the data set.
zhuklara [117]

Answer:

Mean: 50.8 or 51 (rounded)

Median: 51.5 or 52 (rounded)

Step-by-step explanation:

To find the mean I added all the numbers then divides my sum but the number of numbers.

To find the median I listed the numbers from least to greatest.There are two middle numbers so I added the two numbers and divided the same by 2.
