[1] There are two main values to science. The first is that mathematics is where we study numbers... and they appear everywhere in the world around us! We see whole numbers when we count, negative numbers when we are in debt (just look at the national debt!), fractions when we share things between people (think pizza, or chocolate bars, yum!), and decimals when we measure distances, lengths, areas, and sizes. In fact, numbers can be used to describe almost anything. Even color can be described as the amount of red, green, and blue light (the RGB system which is how computer screens work).

The second value to science is the thinking and ideas of mathematics. Mathematics is where we learn the ideas of distance and sizes (such as area and volume). It teaches us to ask, "How far?" or "How big?" These ideas are applied to study geography, biology, astronomy and more. We also learn to look for patterns. In math, these patterns are usually number or geometric patterns, but science applies this idea to discover patterns in the weather, agriculture, oceans, and more.

Charlie is standing 45 feet from the base of 100 foot tall tree. What is the angle of elevation from him to the kite stuck on to

Hey. Let me help you on this one.

In order for us to solve this problem easier, let's break it apart. We can also graph the triangle so we get visual of this problem.

I drew a quick graph for you to easier understand this question. As you can see, Charlie is standing below the tree 45 feet from it, and we need to find the unknown angle measure.

Let's form a SOHCAHTOA function which you have probably already learned in your Geometry course.

First of all let's identify our sides. The side opposite of the right triangle is a Hypotenuse, and the side that's 45 feet is adjacent, since it's adjacent to the unknown angle.

We know that we need to use $Cos$ (Cosine) with negative power to it in order to solve this question, since we are looking for the unknown angle measure.

Let's form the function which $Cos$ , Hypotenuse, and Adjacent side.

$Cos^{-1} =45/100$

Now, let's solve the left part of this function

$
Cos^{-1} =0.45$

Awesome. You will need to use your calculator for this part. Find the value of 0.45 when negative Cosine is used on it.

$Cos^{-1} =0.45$
$63.25631605$

Awesome. Let's round this number to the closest tenth

$63.3$ is the rounded value we have discussed below.

Answer: 63.3 degrees is the unknown measure of the angle

Triss [41]

Add the numbers up to get the total number of biscuits, which will be 50. Then, make a fraction using the squares, which will be 15/50. Simplify by 5. The answer will be 3/10.

Answer:

A) 5.4 cm

Step-by-step explanation:

Length of mid segment = (sum of parallel sides )/2

Sum of parallel sides = PQ + SR = 9 + SR

$\frac{9+SR}{2}=MN\\\\\frac{9+SR}{2}=7.2 cm\\9 +SR = 7.2*2\\\\9 + SR = 14.4\\ SR = 14.4 -9 \\SR = 5.4 cm$
