Let Z = measure of angle Z in terms of sin, cos, and tan.

sin Z = 9/15

cos Z = 12/15

tan Z = 9/12

You can reduce each fraction to the lowest terms if needed.

Solve v^2+2v=0 by factoring

Yuki888 [10]

$\large \mathfrak{Solution : }$

let's factorise :

${v}^{2} + 2v = 0$

$v(v + 2) = 0$

now, there are two cases :

case 1 :

$v = 0$

case 2 :

$v + 2 = 0$

$v = - 2$
