Answer:
x = 11.8639
Step-by-step explanation:
cos∅ = adjacent / hypotenuse
Since we are dealing with right triangles, we can use trig to help solve for missing values:
cos22° = 11/x
xcos22° = 11
x = 11/cos22°
x = 11.8639
The correct answer is A. A whole number
Explanation:
In mathematics, whole numbers include numbers that do not include a fraction, for example, the number 4.2 includes a fraction, and therefore it is not a whole number. Moreover, whole numbers include numbers from 0 to infinity but not negative numbers. This means the number -5 is not a whole number because even then this does not include a fraction it is a negative number. According to this, this number is an integer (it does not include fractions), a rational number (it can be expressed as a fraction), and a real number (it can be represented in a line), but not a whole number.
First of all in order for us to figure out what angle x is we need to find the formula for finding that specific type of angle.
Formula is...
x = (far arc - close arc) ÷ 2
Now we just need to plug in.
x = (172° - 52°) ÷ 2 =
x = 120° ÷ 2 = 60°
Your answer: x = 60°
Good Luck! :)
