If r=10 and s=31, find R. Round to the nearest tenth.

mars1129 [50]

Answer:

C. R = 17.9 degrees

Step-by-step explanation:

We have a rectangle triangle with the adjacent side and the opposite side (neither of which are the hypotenuse).

The relation between those elements is the tangent:

$tan(angle) = \frac{Opposite side}{Adjacent side}$

So, to isolate the angle, we modify the formula as such:

$angle = arctan(\frac{Opposite side}{Adjacent side}) = arctan(\frac{10}{31}) = arctan(0.3225) = 17.87$

If we round 17.87 degrees to the tenth... we get 17.9 degrees.

What is the distance between point A(-3,2) and point B(5,-1)

Gnoma [55]

Remember the distance formula

$S=\sqrt{(5+3)^{2}+(-1-2)^{2} }$

$S=\sqrt{8^{2}+(-3)^{2} }$

$S=\sqrt{64+9}$

$S=\sqrt{73}$
