The sides of a right triangle are related by trig functions of the acute angles. The relationships are described by the mnemonic SOH CAH TOA. The meaning of this is
.. Sin = Opposite/Hypotenuse
.. Cos = Adjacent/Hypotenuse
.. Tan = Opposite/Adjacent
Here, you are given the adjacent side and the hypotenuse for the angle. This means you can use the relation
.. Cos = Adjacent/Hypotenuse
Putting in the given information lets you find x.
.. cos(22°) = x/11
.. 11*cos(22°) = x ≈ 10.199
Answer:
ok the rest
Step-by-step explanation:
They equal the same amount (3) but are written out in different ways.
Answer:
150=
x, or 4(150)=x
Step-by-step explanation:
Let's use x to represent the total number of pages in the book.
If 150 is a quarter of the whole book, then 150 is equal to a quarter of x
150= .25(x)
We an go further and multiply both sides by 4 to cancel the .25
4(150)=x
We can finish solving and x=600 pages
