What’s the answer to this question

Step-by-step explanation:

Here, in the triangle ABC. Base = 5 units.

Let, Perpendicular = k units. Hypotenuse = 13 units. In a Right angle triangle, by PYTHAGORAS THEOREM:

Similarly, in triangle ABC. or, ⇒ ⇒ k = 12, or k= -12. But as k is the length of a side of a triangl.

a is the right answer

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
