Congruent means like the same thing so i would say the 2 right one which might be (B and D i guess) hope it helps and have a great day
Cool you're in K12 so am I. <span />
<span>if a trip from earth to mars, is 97/186=.52150
and
a trip from earth to venus is 0.2774(now we have to times it by 2 since its a roundtrip),
we get .5548
we can clearly see that .5548>.52150
So roundtrip venus</span>
There is an 80% chance that it is red or green.
You would get $46.40 back.
Just do 192x0.80=153.60
Then subtract 200-153.60
Answer:
As per the given condition: Rodrigo has a ladder that is 13 ft long. The ladder is leaned against a vertical wall. The top of the ladder is 10.8 ft above the ground.
The Orientation of the ladder with the wall forms a right triangle.
The ladder length is the hypotenuse of the triangle,
the distance between the ladder at ground level and the base of the wall is the horizontal leg of the triangle,
and the height of the ladder is the vertical leg of the triangle.
⇒ Height of the ladder = 10.8 ft and hypotenuse = 13 ft
Using sine ratio formula;

Opposite side = height of the ladder = 10.8 ft and
Hypotenuse side = 13 ft.
then;

or

Simplify:
(nearest to tenth place)
Since, it is given that the angle the ladder makes with the ground needs to be 60 degree or less for safety purposes.
(a)
Yes, this ladder in a safe position.
as 
(b)
You can see the diagram as shown below in the attachment.
