In the triangle below, what is cos B?
2 answers:
Cos B = c/a
cosine is adjacent over hypotenuse.
there is an acronym for this: soh-cah-toa
soh: sine is opposite over hypotenuse
cah: cosine is adjacent over hypotenuse
toa: tangent is opposite over adjacent
Answer:
Step-by-step explanation:
We have been given a triangle. We are asked to find .
We know that cosine relates adjacent side of a right triangle to its hypotenuse.
We can see that side AB is adjacent side and CB is hypotenuse of our given right triangle.
Therefore, our required value is

Answer:
x = 5
Step-by-step explanation:
3x - 7 + 4x = 28
Combine like terms
7x -7 = 28
Add 7 to each side
7x - 7 +7 = 28+7
7x = 35
Divide each side by 7
7x/7 = 35/7
x = 5
