Answer:
13.7 units
Step-by-step explanation:
Hi there!
The dotted lines and the hypotenuse of the green triangle create a new right triangle, with one of its acute angles measuring 17 degrees and its hypotenuse measuring 47 units.
Given this information and that we must solve for the side opposite the given angle, we can use the sine ratio:

Plug in known information

Therefore, the value of x when rounded to the nearest tenth is 13.7 units.
I hope this helps!
Providing a short wikipedia definition here: "In mathematics, a rational number is any number that can be expressed as the quotient or fraction"
So any fraction would work for this question I believe?
Answer:
It is right
Step-by-step explanation:
square all sides
we have 16, 32, 48
add the two shortest sides, which equal the third side
the triangle works with the pythagorean theorem, so of course it is right :)
Number 9 is 36 because there are 18/40 who feel safe, so it multiplied would be 36. C
