Answer:

Step-by-step explanation:
Solve the following inequality:

-Take
and subtract it from
:


-Subtract
on both sides:


-When you are dividing an integer by a negative integer, then the inequality sign changes. So, Take
and divide it on both sides:


Therefore, the answer is
.

Step-by-step explanation:
Answer:
A cos C = 12/13
Step-by-step explanation:
cos theta = adjacent side/ hypotenuse
cos C = BC/AC
But we don't know BC, but we can find it using the Pythagorean theorem
a^2 +b^2 = c^2
5^2 +BC^2 = 13^2
25 + BC ^2 =169
Subtract 25 from each side
BC^2 = 169-25
BC ^2 = 144
Taking the square root of each side
BC =12
cos C = 12/13
