Question

Help with geometry hw

Answer 1

1) 18

2) 6

3) 12

4) 12

5) 7

6) 9

Explanation:

1) 2*x = 6^2, 2x=36, x = 18

2) 2*(x+2) = 4^2, 2x+4 = 16, x = 6

3) 10^2 = 5 * (x+8), 100 = 5*(x+8), x = 12

4) The altitude is 4sqrt3 using pythagorean, (4sqrt3)^2 = 4*x, 48 = 4*x, x=12

5) Altitude is sqrt63 using pythagorean, (sqrt63)^2 = 9x, x = 7

6) Altitude is sqrt72, sqrt(72+9) = 9
