Step-by-step explanation:
Answer:
sin(D) = cos(F)
cos(D) = sin(F)
tan(D) = 1/tan(F) which means tan(F) = 1/tan(D)
Step-by-step explanation:
First it is important to know that the sine of an angle is the fraction of the opposite side over the hypotenuse side, while cosine is the adjacent over the hypotenuse and finally tangent is opposite over adjacent. You can't take the sine, cosine or tangent of the right angle like this though.
sine is o/h
cosine is a/h
tangent is o/a
So let's do each angle.
Keep in mind E is the right angle so we can't take any trig function of it with SOH CAH TOA so let's do D first.
D has an adjacent side of f since e is the hypotenuse, which leaves d as the opposite so lets go throught he trig functions.
sin(D) = d/e
cos(D) = f/e
tan(D) = d/f
Now let's do the same with F. d is adjacent, e is the hypotenuse and f is opposite.
sin(F) = f/e
cos(F) = d/e
tam(F) = f/d
Now, you can actually match them up
sin(D) = cos(F)
cos(D) = sin(F)
tan(D) = 1/tan(F) which means tan(F) = 1/tan(D)
And just looking at that we've answered the question. let me know if that doesn't make
We are given that Addison wants to cut 21 centimeters of lace. The question asks us to convert 24 centimeters into millimeters. However, to do that, we need to know how many millimeters are in a centimeter. There are 10 millimeters in a centimeter. Since centimeters are larger, we will need to multiply. Therefore, 21 × 10 is 210 millimeters, and that is how many millimeters Addison wanted to cut. Hope this helped and have a phenomenal day!
Answer:
you have it right, its 60. since all sides are equal, then all angles must be equal. triangles are 180, so 180 divided by 3= 60
