A radio station is going to construct a 5-foot tower on top of a building. the tower will be supported by three cables, each att
KonstantinChe [14]
You need to use Pythagoras’ Theorem. 
A² + B² = c² and c is the hypotenuse of the right angled triangle.

The height of the tower (5 feet) is A and the distance from the end of the cable and the base of the tower (12 feet) is B. The length of ONE cable is c. So:

A² + B² = c²
5² + 12² = c²
25 + 144 = c²
169 = c²
13 = c. This is the length of one cable.

3 x 13 = 39 therefore the total length of the cables is 39 feet.

A kangaroo hops 2 kilometers in 3 minutes. At this rate:
nikitadnepr [17]
It takes 7 minutes and 30 seconds to travel 5 kilometers because first you divide 3 and 2 to figure out how many minutes is 1 kilometer and you get 1.5 then you multiply 5 and 1.5 to get the minutes of 5 kilometers. Also the kangaroo travels 1.3 kilometers in 2 minutes
