Answer 1

8) x = 3

9) x = 10

Explanation:

8) 45° ≅ 15x, therefore, the equation would look like:
`45 = 15x`

☆Let's solve it!

`(45)/(15) = (15x)/(15) \\ 3 = x`

9) 12x - 10 is supplementary to 8x - 10. So the equation would be:
`12 x- 10 + 8x - 10 = 180`

☆Let's solve it!

`12x - 10 + 8x - 10 = 180 \\ 20x - 20 = 180 \\ ( \: \: \: \: \: \: \: \: \: \: + 20 = + 20)/( (20x)/(20) = (200)/(20) ) \\ x = 10`

Answer 2

8) 45/15
3

x = 3
