Answer:

A) 5x-7y=42

Step-by-step explanation:

We know that 5 x 7 = 35 then add 7 = 42

We divide 5 and 7 by 5/7

5/  5/7 = 0.1

7/ 5/7 = 0.2

We find 0.1 = 1/10 and we know that 1/10 of 35 is 3.5

We find 0.2 = 2/10 and we know that 2/10 of 35 is 7 so the answer 7 matches.

We then use 7 for y and keep 5 for x.

55° is equal to 0.9599 radians.  

Step-by-step explanation:  

Step 1:  

If an angle is represented in degrees, it will be of the form x°.  

If an angle is represented in radians, it will be of the form \frac{\pi}{x}radians.  

To convert degrees to radians, we multiply the degree measure by \frac{\pi}{180}.

For the conversion of degrees to radians,

the degrees in radians = (given value in degrees)(\frac{\pi}{180}).

Step 2:

To convert 50°,  

55\left(\frac{\pi}{180}\right)=\frac{55\pi}{180}.

0.3055 (\pi) =0.9599 radians.

So 55° is equal to 0.9599 radians.

How do I solve this?
Serhud [2]

Answer:

44.94

Step-by-step explanation:

Use trigonometric ratios to find the unknown side.

Since you are given the adjacent side and the opposite side is in question, use the tangent ratio.

tan(x) = opposite/adjacent

Replace the variables with given values.

tan(59) = x/27

Isolate the variable.

27tan(59) = x

Use a calculator to evaluate the answer.

x = 27tan(59) ≈ 44.94
