Use a table of trigonometric values to find the angle è in the right triangle in the following problem. Round to the nearest degree, if necessary.
cos è=? A=22 H=38
Not being able to see your diagram, I will assume that A stands for adjacent, and H stands for hypotenuse
so ....
cos è = 22/38 = .578947...
è = 54.623..
so to the nearest degree è=55°
4.735
Oh, a trigonometric question! Let me get my table and clown nose ready. Now, to find the angle è, we need to use the cosine function, which is adjacent over hypotenuse. In this case, we know the adjacent side is 22 and the hypotenuse is 38. So, let's divide 22 by 38:
cos è = 22/38
Pulling out my trusty calculator, that gives us approximately:
cos è = 0.579
Now, let me put on my jokester hat and tell you that è must've gone on a vacation because I couldn't find it in my clown dictionary! But don't worry, we were only looking for the value of cos è, which is 0.579 (rounded to three decimal places).
Hope that brings a smile to your face!
To find the angle è in the right triangle, we can use the cosine function. The cosine of an angle is equal to the length of the adjacent side divided by the length of the hypotenuse.
In this case, we're given the adjacent side length A as 22 and the hypotenuse length H as 38.
Using the cosine function, we can find the value of cos è:
cos è = A / H
cos è = 22 / 38
cos è = 0.57895 (rounded to 5 decimal places)
Now, we can use a table of trigonometric values to find the approximate angle corresponding to this cosine value.
Looking up the value 0.57895 in a table, we find that it corresponds to an angle of approximately 55 degrees.
Therefore, the angle è in this right triangle is approximately 55 degrees.
To find the angle è in the right triangle, we can use the cosine function. The cosine function relates the adjacent side (A) and the hypotenuse side (H) of a right triangle.
Here is the formula for the cosine function:
cos è = A / H
In this case, A = 22 and H = 38. Let's substitute the values into the formula:
cos è = 22 / 38
To find the value of cos è, we divide the length of the adjacent side by the length of the hypotenuse. Using a calculator, we get cos è ≈ 0.57894736842.
To find the value of the angle è, we can use the inverse cosine function (also known as arccosine or cos⁻¹). Taking the inverse cosine of 0.57894736842, we can find the angle in degrees.
Using a calculator, we find è ≈ 55 degrees (rounded to the nearest degree).
Therefore, cos è is approximately 0.579 and the angle è is approximately 55 degrees.
