Find the missing side b. Round your answer to the nearest tenth if needed

Mathematics
1 answer:
Citrus2011 [14]3 years ago
4 0

Answer:

  b = 20

Step-by-step explanation:

This is a right triangle with the ratio of the given sides being ...

  15 : 25 = 3 : 5

This means it is a 3:4:5 right triangle. The side ratios are ...

  a : b : c = 3 : 4 : 5 = 15 : 20 : 25

The missing side length is b = 20.

__

You can also figure this using the Pythagorean theorem.

  c² = a² + b²

  25² = 15² +b²

  625 -225 = b² = 400

  b = √400 = 20

The missing side length is 20.

What is the length of a kite string that is 6 meters above and 9 meters away from where it is being held? Round to the nearest t
ivann1987 [24]

Answer:

10.8 meters

Step-by-step explanation:

This situation forms a right triangle, where the length of the kite string is the hypotenuse, the distance from where it is held is the long leg, and the height is the short leg.

Use the pythagorean theorem to solve for c, the length of the kite string.

a² + b² = c²

6² + 9² = c²

36 + 81 = c²

117 = c²

10.8 = c

So, the length of the kite string is 10.8 meters
