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
So, cos (L) would be
cos(L)=base/hypotenuse
cos(L)=5/13
Hence, First option is correct.

Answer: 72
Step-by-step explanation:
Prism area = b * h
base = 4 * 3 = 12
height = 6
12 * 6 = 72
Answer:
4(7y - 9)
Step-by-step explanation:
The greatest common factor you can factor out of both monomials is 4.
28y - 36
4(7y - 9)
Answer:
0.9
Step-by-step explanation:
To find the mean temperature, we have to add all of the numbers together and divide that by the amount of numbers there are.
6 + 5 + 3 + -4 + 3 + -3 + 2 + -1 + -2 + 0 = 9
There are 10 numbers.
Our mean, or average, would be 9 / 10 = 0.9
13 inches is the length of 1 side. You find this by doing to square root of 169.
