Find the value of X in that isosceles triangle shown below

ipn [44]

Answer:

sqrt(13) =x

Step-by-step explanation:

We have 2 right triangles, one on the right and one on the left

The base is 1/2 of 4 or 2 and the height is 3

We can use the Pythagorean theorem to find the hypotenuse

a^2 + b^2 = c^2

2^2 + 3^2 = x^2

4+9 = x^2

13 = x^2

Take the square root of each side

sqrt(13) =x

How many ways can a committee chairman choose 4 people for a subcommittee if there are 12 members on the whole committee?

Marina86 [1]

A group of k elements can be chosen from a group of n elements in $\frac{n!}{k!(n-k)!}$ ways.

$(^{12} _4)=\frac{12!}{4!(12-4)!}=\frac{12!}{4! \times 8!}=\frac{8! \times 9 \times 10 \times 11 \times 12}{2 \times 3 \times 4 \times 8!}=\frac{9 \times 10 \times 11 \times 12}{2 \times 3 \times 4}= \\ \\
=3 \times 5 \times 11 \times 3=495$

The answer is B. 495.
