Tan 30(degrees) = 7/x x = 7 / tan 30 (degrees) 12.1

The other answer here says it is 45 degrees of elevation. This is the basic SOH-CAH-TOA formula that most of us learn in geometry at the end of the year. So, many of us don’t remember how to do it. You want to use the TOA part of the formula; this is also called the tangent. So, you solve for the tangent and voila. There’s your angle: 45 degrees. Doing so is easy. First, you divide the opposite side by the adjacent side. Then, you use the tan-1 function on a calculator to get the final answer. For this particular problem, that’s 10/10 = 1. Using the tan-1 function, you get a 45.0 answer (corrected to one decimal point, but you get the idea.)

The length of line from B which is perpendicular to line AC is 75cm

In math, it is common to measure angles. One way to do this is to use some of the math facts that are known about angles. A right corner is always going to be ninety degrees. Therefore, if you know the measurement of one aspect within a right angle, then you should know the other angle because it would be that measurement subtracted from ninety degrees. So, if there is a right angle and it is split into two unequal angles, then you may be able to determine its measurement since one angle is measured. The size of one aspect is thirty-two degrees. Therefore, ninety minus thirty-two is fifty-eight degrees. So, angle b is fifty-eight degrees. A straight line is one hundred eighty degrees.

The correct answer to this question is E, 954km, 133. This question would be found on math tests, specifically in Trigonometry courses. This word problem deals with bearings, which are angles used in navigation. Bearings are angles in degrees, which are measured clockwise from North. For example, 20 degrees clockwise North would be written out as 020 degrees. There are two rules used to solve bearings. The first is the cosine rule, which is used when you have the two sides and the angle, but need to find the third side or when you know the three sides but need to find the angle. The second rule is the sine rule, which is used when you know one side and the three angles and need to find another side or when you know the two sides and an angle, but need to know the other angle.

1 should be 70 not 070

D is the answer to this question. You need to look at the diagram and the different numbers that are given to come up with the solution. A lot of people do not think that trigonometry is going to be important in their lives, but actually, this is something that can be useful for people who plan on building careers that involve calculating angles and triangles. This is a skill that people can learn when they study trigonometry. Basic trigonometry can be acquired at an early age, but the more advanced versions can become available in the long run. Without proper knowledge, some people may fail at doing their tasks.

There are different methods that are used by people in order to calculate the distance and bearing of objects. Some people use the VIncenty’s formula. This would require converting the longitude and latitude before everything will be computed. If this formula will be used, the answer to this question is letter E. There are some who use other models in order to form computations that will help them arrive at the answer. Computing for distance and bearing may be complicated if you do not know the step by step process. It is ideal that you know each step properly so you can continue without any issues.

How can i solve it

I don't understand how you get this answer, I got 24.8. Can someone please explain this to me

In order to find the sine of an angle, you must know the lengths of the opposite side and the hypotenuse. You will always be given the lengths of two sides, but if the two sides aren’t the ones you need to find a certain ratio, you can use the Pythagorean theorem to find the missing one.
