Answer:
The distance of the foot of the ladder to the building is 14 ft.
Step-by-step explanation:
The length of ladder = 20 ft
Angle formed by ladder with level ground, θ = 46
We are required to find out the distance of the foot of the ladder from the building
The above question can be found out by using trigonometric relations as follows;
The adjacent side of the right triangle formed by the ladder the building and the ground is the distance of the foot of the ladder from the building
The hypotenuse side is the length of the ladder = 20 ft
Therefore;
Adjacent side of triangle = Hypotenuse × cosθ
∴ Distance of the foot of the ladder from the building = Hypotenuse × cosθ
Distance of the foot of the ladder from the building = 20 ft × cos(56)
Distance of the foot of the ladder from the building = 13.893 ft
To the nearest foot, the distance of the foot of the ladder to the building = 14 ft.
Answer: 455 mph
Step-by-step explanation:
if train one is traveling one way at 60mph, then you have to multiply that by 3.5 to see how far it traveled in that amount of time.
60 x 3.5 = 210
then, you have to multiply 3.5 by 70mph, to see how far the second train has traveled in that amount of time
70 x 3.5 = 245
finally, since both trains are moving in opposite directions, you have to add up the distances together to get the final difference
210 + 245 = 455
Answer:
C. you can not prove that the triangles are congruent
Step-by-step explanation:
- The answer can not be SAS becuase although the congruent angle is not in between the two congruent sides.
- It can not be AAS because only one angle is congruent.
- It can not be SSS because all three sides are not congruent.
