Answer:

C. 5

Step-by-step explanation:

Use the Distance Formula.

Substitute the values of x1 , y1 , x2 , and y2 .

|AB|² =|(1--2)²+(10-6)²|

|AB|² = |9+16|

|AB| = √ 25

|AB| =5

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.

Find the measure of angle TUV

denpristay [2]

Answer:

∠TUV = 120°

Step-by-step explanation:

Since this figure is a kite, we know that; ∠TUV ≈ ∠TWV, so first we solve for x:

9x - 6 = 7x + 22

2x - 6 = 22

2x = 28

x = 14

Now, substitute 14 in for x, in the equation for ∠TUV:

∠TUV = 9x - 6

∠TUV = 9(14) - 6

∠TUV = 126 - 6

∠TUV = 120°

Hope this helps!
