Answer:
Step-by-step explanation:
For this exercise you need to use an Inverse Trigonometric Function called "Arctangent".
By definition:
You must observe carefully the triangle PQR shown in the picture attached.
In this case you can identify that:
Therefore, knowing those values you can substitute them into , as following:
Finally, evaluating, you get that the measure of the angle R is the following:
Rounding to the nearest tenth:
Assuming the rule is multiply by 6, I would say 216.
Answer:
2√3
Step-by-step explanation:
So √12 is in radical form. I think what you are asking for is to reduce the expression to its **simplest** readical form.
So 12 = 4*3, √12 = √4 * √3.
So 12 = 4*3, √12 = √4 * √3.
We can ‘reduce’ this by noting that √4 =2, so the expression becomes 2√3.
This cannot be further reduced because 3 isn’t a square or divisible by a square, so 2√3 is the simplest radical form.
I think it would be x=-4 and y=-1
