In some trigonometry classes, this acronym is very important to solving questions like this.
Why?
It tells us the right triangle-definition of these trigonometry functions.
We have that cosine of an angle is equal to tge side that is adjacent to it over the hypotenuse.
So here we are asked to find cos(B).
Lets look at triangle respect to the angle B
The measurement of the side that is opposite is 64.
The measurement of the side that is adjacent is 48.
The measurement of the hypotenuse is 80.
So cos(B)=48/80.
Let's reduce. 48 and 80 have a common factor of 8 so divide numerator and dexter by 8. This gives us:
cos(B)=6/10.
One more step in reducing. Both factors are even so cos(B)=3/5.
Answer: 16 different ways
Step-by-step explanation:
Hello there! 6.487 rounded to the nearest hundredths place is 6.49 and 2.049 rounded to the hundredths place is 2.05. The sum of these numbers is 8.54.
Remember: If the number value after the value you are rounding is equal to or greater than 5, round up. If it is less than 5, round down.
With this in mind, let's round the numbers:
First: 6.487 rounded to the hundredths place would be 6.49, since 7 is greater than 5.
Second: 2.049 rounded to the hundredths place would be 2.05, since 9 is greater than 5.
Next, we will add the numbers together
2.05 + 6.49 = 8.54.
So, this is our final answer. I hope this answers your question & have a great day! :)
