Answers
The length of PR is 4.4 units.
Explanation:
It is given that the length of the hypotenuse is 10 units.
Also, the angle of R is 64°
To find the length of PR, we shall use the cosine formula,
Here, , adj = PR and hyp = 10
Substituting these values in the formula, we get,
Multiplying both sides by 10, we get,
Substituting the value for cos 64, we get,
Multiplying, we have,
Rounding off, we get,
Thus, the length of PR is 4.4 units.

1/2=0.5
3/4=0.75
Now we just have choose a random decimal in between the decimal.
Let's choose 0.6
Now we have to convert the decimal into a fraction. So we'll multiply the decimal by100.
0.6×100=60
Then we make the 60 into a fractions. 60/100
Then we'll simply the fraction. 60/100÷10=6/10÷2=3/5
There you go. You have your answer.

twenty problems on your own, and you decided to just dump them on Brainly.
I'm also disappointed that yuu thought the whole thing is only worth 11 points.
I'll do a substantial amount of each problem, but not all of it.
Some of the contribution should be yours.
This whole page is just a bunch of exercises for one fact:
(any difference of two squares) is equal to
(the sum of the square roots of the terms)
times
(the difference of the square roots of the terms) .
That's the solution to everything on the page, right there.
OK. Here we go:

16). (7m² + 4) (7m² - 4)
17). (k³ + 4) (k³ - 4)

20). (8m² + 3n) (8m² - 3n)
You can do the FOIL checking. I buried one error in there
just so that you'd have something to look for and fix.
