-5 is the adjacent side, -12 is the opposite side, the hypotenuse is 13
Cos = adjacent/hypotenuse
Cos = -5/13
The answer is C.

Answer:

x = 58 degrees

Step-by-step explanation:

Angle K (which is x) and Angle I are congruent corresponding angles with one another, so if, as an example, Angle I was 10, Angle K would also be 10.

All you need to do in this case is add Angle H (56) and Angle A (66) together:

56 + 66 = 122

Then subtract 122 from 180 (because triangles add up to 180 degrees) to get x:

180 - 122 = 58

So, x = 58 degrees.

Answer:

x + 14.7

Step-by-step explanation:

Simply combine like terms. Constants go with each other and x terms go with each other.

6.2 + 8.5 = 14.7

x = x

x + 14.7

which inequality represents the following situation 3/5 times 5 less than a number is no more than 27

andrey2020 [161]

The answer is $\frac{3}{5}(x-5) \leq 27$

Let's build the expression piece by piece, translating sentences into formulas:

"3/5 times..." $\to \frac{3}{5} \times \ldots$

"5 less than a number..." $\to x-5 \ldots$

So, the first block becomes

"3/5 times 5 less than a number..." $\to \frac{3}{5}(x-5) \ldots$

"...is no more than 27" $\ldots \leq 27$

So, putting the pieces together, you have the answer
