1) Altitude creates a right triangle with hypothenuse = 13, and one leg = 1/2 base = 5. So 13^2 – 5^2 = h^2, and 144 = h^2. so h = 12

2) Square root of a negative number is imaginary — irrational, but not in the real number system.

3) +/- 6

4) assume you mean sqrt(9/16) = +/- 3/4

5) this is the cube root of 1/64, and = 1/4

find the altitude of a triangle with sides of 13 each and a base of 10.

The altitude divides the original triangle into two right triangles, each with base 5 and hypotenuse 13.

Let the altitude be x.

13^2 = 5^2 + x^2

169 = 25 + x^2

144 = x^2

x = 12
