Answer:
I believe what you would have to do is add each number so the top left box would be two and the bottom right would be 11

Answer: x = 19.7 (choice C)</h3>
=========================================================
Explanation:
The reference angle is 24 degrees. Opposite that angle is the side 8 units long. The horizontal portion is unknown and it's the adjacent side.
Also unknown is the value of x which is the hypotenuse.
To summarize:
- opposite = vertical leg = 8
- adjacent = horizontal leg = unknown
- hypotenuse = x
The hypotenuse is always opposite the 90 degree angle.
To tie together the opposite and hypotenuse, we'll use the sine ratio
sin(angle) = opposite/hypotenuse
sin(24) = 8/x
x*sin(24) = 8
x = 8/sin(24)
x = 19.6687 approximately
x = 19.7 after rounding to the nearest tenth.
Side note: your calculator needs to be in degree mode
Answer:
All real numbers
Step-by-step explanation:
Domain = x values.
There is no limitation on x-values.
8+(16)/4 (divide 16 and 4 first, PEMDAS)
8+4 (add these two together)
12
I'm sure the answer is x=8
