a tree struck by lightning broke at a point 12 feet above the ground.
what was the height of the tree to the nearest tenth of a foot?
explain your reasoning.

height of the tree was 52.8 feet

Step-by-step explanation:

Height of the tree will be determined by adding broken part of the tree, lying on the ground (as the hypotenuse of the triangle) and the remaining part of the stem.

Now we apply Pythagoras theorem in the right angle triangle with the sides as 12 feet and 39 feet

⇒ Hypotenuse² = Base² + Height²

⇒ Hypotenuse² = 12² + 39²

⇒ Hypotenuse² = 144 + 1521 = 1665

⇒ Hypotenuse = √1665

                         = 40.80 feet

Now height of the tree = 12 + 40.8

= 52.8 feet

Therefore, height of the tree was 52.8 feet

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
