Answer:

4. x = 16.8

5. x = 35.98

Step-by-step explanation:

For both triangles that you need to work on, use the trigonometric function which is tan and you are dividing opposite by adjacent for the answers.

For number 4, the equation you are setting up is tan 35 = x/24. Multiply 24 on both sides to get the answer which is 16.8 for the x side.

For number 5, the equation you are setting up is tan 17 = 11/x. As a result on your calculator, you should get 35.98 for the x side.

Kanye wants to make a triangular flower bed using logs with the lengths 3 ft, 4 ft, and 8ft. Can Kanye form a triangle with the

valina [46]

Way 1:
a triangle with sides 3,4,5 will make a triangle. because this isn't 3,4,5 triangle it wont work.

way 2:
By using Heron's formula you can find the area of the flower bed.
s=(a+b+c) ÷2
Area =√s(s-a)(s-b)(s-c)
so, 3+4+8= 15
15÷2 =7.5
√7.5(7.5-3)(7.5-4)(7.5-8)
Now because 7.5-8 gives you a negative number and you can't have a negative number under a square root unless you want to use an imaginary number, it won't form a triangle.

Answers:

In these exercices are ilustrated the representations of the fractions

2) Firstly, we have 3 equal segments, each one representing $\frac{1}{4}$ , hence:

$\frac{3}{4}$ is 3 copies of $\frac{1}{4}$

Let's prove it, taking into account we are adding fractions with the same denominator:

$\frac{1}{4}+\frac{1}{4}+\frac{1}{4}=\frac{3}{4}$

There are 4 equal parts that make a whole

Four copies of $\frac{1}{4}$ make $\frac{4}{4}$ or 1 whole

$\frac{1}{4}+\frac{1}{4}+\frac{1}{4}+\frac{1}{4}=\frac{4}{4}=1$

3) Here we have a line divided into four segments, each one of $\frac{1}{5}$ . Hence:

This is $\frac{4}{5}$ of a line. $\frac{4}{5}$ is 4 lengths of $\frac{1}{5}$

$\frac{1}{5}+\frac{1}{5}+\frac{1}{5}+\frac{1}{5}=\frac{4}{5}$

If we draw one more $\frac{1}{5}$ we will have $\frac{5}{5}$ or 1 whole.

Then:

5 lengths of $\frac{1}{5}$ make $\frac{5}{5}$ or 1 whole.

4) In this part the answer is in the attached image. If we have two equal segments, each one of $\frac{1}{3}$ we will have as a result $\frac{2}{3}$ .
