Answer:

The answer to your question is TV = 7.8

Step-by-step explanation:

Data

hypotenuse = ?

Opposite side = 4

angle = 31°

To solve this problem use trigonometric functions. The trigonometric function that relates the Opposite side and the hypotenuse is sine.

sin $\alpha = \frac{Opposite site}{hypotenuse}$

Solve for hypotenuse

hypotenuse = $\frac{Opposite side}{sin \alpha}$

Simplification

hypotenuse = $\frac{4}{sin 31}$

hypotenuse = $\frac{4}{0.52}$

Result

hypotenuse = 7.76

ABC is reflected across x = 1 and y = -3. What are the coordinates of the reflection image of B after both reflections?A. (-7, -

Dima020 [189]

Answer:

The correct option is C.

Step-by-step explanation:

From the given figure it is noticed that the coordinates of B are (-5,-7).

If ABC is reflected across x = 1, then

$(x,y)\rightarrow(1-(x-1),y)$

$(x,y)\rightarrow(2-x,y)$

$(-5,-7)\rightarrow(2+5,-7)$

$(-5,-7)\rightarrow(7,-7)$

If ABC is reflected across y =-3.

$(x,y)\rightarrow(x,-3-(y-(-3)))$

$(x,y)\rightarrow(x,-6-y)$

$(7,-7)\rightarrow(7,-6-(-7))$

$(7,-7)\rightarrow(7,1)$

Therefore option C is correct.

We can do S=1/2 of (4x+2)+4 * (3x+1) +4. All we are doing is adding 4 feet. I believe you are able to simplify it to 1/2 of 4x+6 * 3x+5
