Answer:
Total number of matches = 306 matches
Step-by-step explanation:
Given:
Total number of team = 18
Per team number of play = 2
Find:
Total number of matches
Computation:
Total number of matches = [(Total number of team x 2)(Total number of team -1)]/2
Total number of matches = [(18 x 2)(18-1)]/2
Total number of matches = 612 / 2
Total number of matches = 306 matches
Answer:
Explanation:
The <em>guy-wire</em>, the highest point of the <em>cell phone tower</em>, and the the <em>point on the ground that is 25 ft from the base of the tower</em> form a right triangle, where:
- the <em>length of the guy-wire</em> is the hypotenuse of the triangle
- <em>the height of the cell phone tower </em>is one leg (75 ft)
- the distance from the <em>point on the ground to the base of the tower</em> is the other leg (25 ft).
Since you know the lengths of both legs, you can use Pythagora's theorem to find the hypotenuse (the lenght of the guy-wire):
