Answer:

x = 12.2

Step-by-step explanation:

sin theta = opp / hypotenuse

sin 55 = 10 /x

Multiply each side by x

x sin 55 = 10

Divide each side by sin 55

x = 10 / sin 55

x =12.20774589

Rounding to the nearest tenth

x = 12.2

The horizontal beams are what I like to think of as "rail road tracks". The metal portion of the tracks anyway. Notice how angle 2 and angle 8 are inside the tracks, so we consider them "interior angles"

Furthermore, they are on opposite or alternate sides of the transversal line. The transversal line is the non-parallel line that cuts through the "rail road tracks".

Put those two facts together and we get "alternate interior angles" as our final answer

What is the reflection image of P(0, 0) after two reflections, first across x = 4 and then across y = -3?

jek_recluse [69]

Answer:

The reflection image of P(0, 0) after two reflections is (8,-6)

Step-by-step explanation:

step 1

Find the coordinates of point P after reflection across x=4

we know that

The distance from point P to the line x=4 is equal to 4 units

(0,0) -----> (4+4,0) ----> (8,0)
