( | 180 | + | x | ) | ÷ | ( | 180 | - | x | ) | = | 3 2 |
Multiply both sides of the equation by: | ( | 180 | - | x | ) |
( | 180 | + | x | ) | = | 3 2 | ( | 180 | - | x | ) |
180 | + | x | = | 3 2 | ( | 180 | - | x | ) |
180 | + | x | = | 3 2 | × | 180 | - | 3 2 | x |
180 | + | x | = | 270 | - | 3 2 | x |
x | + | 3 2 | x | = | 270 | - | 180 |
5 2 | x | = | 270 | - | 180 |
5 2 | x | = | 90 |
x | = | 90 | ÷ | 5 2 |
= | 90 | × | 2 5 |
= | 18 | × | 2 |
x | = | 36 |
