Answer:

r = 8

Step-by-step explanation:

you start by distributing the 5 to r and -7 to get 3 over 5r - 37. You can then multiply both sides by 5r-37 to get 3 = 5r-37. From here you can add 37 to both sides to get 40 = 5r. From there you divide both sides by 5 to get r = 8

Given right triangle JKL, what is the value of cos(L)?
Daniel [21]

First option is correct.

Since we have given that

JKL is a right triangle.

Length of JK = 12

Length of KL = 5

By Pythagoras theorem, we get that

JL^{2}=JK^{2}+ KL^{2}\\JL^{2}=12^{2}+ 5^{2} \\JL^{2}=144+25= 169\\JL=13

So, cos (L) would be

cos(L)=base/hypotenuse

cos(L)=5/13

Hence, First option is correct.

Geometry question. please help ​
Vinvika [58]

Answer:

The length of PQ is <u>18</u> feet.

The length of PR is <u>18</u> feet.

The length of QR is <u>24</u> feet.

Step-by-step explanation:

A way to set an equation up for this problem is:

\frac{4}{3}x+x+x=60

where x is the three lengths of the isosceles triangle, but the base QR is 4/3 the length of the other two congruent sides, length PQ and PR. The 60 represents the total length of the perimeter.

Then, solve for x from the equation, and you’ll get x=18. But your not done yet. Since the variable x in the equation stands for the sides of the isosceles triangle, so plug 18 into the equation and it should look like this:

\frac{4}{3}(18)+18+18=60

Don’t solve the whole equation, just solve the \frac{4}{3}(18) part of the equation, which is equal to 24. So the final equation is this:

24+18+18=60

Conclusion: 24 is the length of QR, and 18 is the length of PQ and PR. And they all equal 60, which is the perimeter. This is very true because the length of PQ and PR are the same (length 18), since it’s an isosceles triangle, and the length of QR is 4/3 the length of PQ and PR (4/3 of 18= 24).

Sorry for the long explanation.

But hope this helps and answers your question :)
