Answer:

x = 3

Step-by-step explanation:

Given

-2(x + 5) = -16

Expand the bracket

-2 x X +-2 x 5 = 16

The positive sign changes to minus

-2x - 10 = -16

Add 10 to both sides

-2x -10 + 10 = -16 + 10

-2x = -6

Divide both sides by-2

x = -6/-2

x = 3

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.
