Answer:

1 unique

Step-by-step explanation:

Given the angles of the triangle in the question, only one unique triangle can be formed.

This is because, if we look at the angles given, we can see that we have two of the angles equal.

This will give rise to the formation of an isosceles triangle which is a triangle in which two of the sides are equal in length

The equal angles made it in such a way that this is the only type of triangle that can be formed from the angles given

Simplify the square root of -121?

poizon [28]

Answer:

11i

Step-by-step explanation:

first you have to get a postive root.

$\sqrt{-121} \\ \sqrt{-1} \sqrt{121} \\$

then you solve the square roots from there, keeping in mind the imaginary number answer to the square root of -1, i.

$\sqrt{-1} = i\\ \sqrt{121} =11\\ 11i$

Anita plans to give her husband 3 shirts for his birthday. She narrows the search to 3 shirts from a selection of 17 shirts at D

Lunna [17]

Using the combination formula, it is found that she can select the shirts in 775,200 ways.

The order in which the shirt are chosen is not important, hence, the combination formula is used to solve this question.

Combination formula:

$C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by:

$C_{n,x} = \frac{n!}{x!(n-x)!}$

In this problem:

3 shirts from a set of 17.

Then, 3 shirts from a set of 20.

They are independent, hence, to find the total, we multiply both combinations.

$T = C_{17,3} \times C_{20,3} = \frac{17!}{3!14!} \times \frac{20!}{3!17!} = 680 \times 1140 = 775200$

She can select the shirts in 775,200 ways.
