The first option is correct.
Step-by-step explanation:
how do we multiply x - 9 by something? we put it in brackets
(x - 9) × (-3) = 51
that can be written like this
(x - 9)(-3) - 51
x = 6
Since the triangles are similar, we can use ratios to solve
20 24
--------- = ---------
5 x
Using cross products
20x = 24*5
20x = 120
Divide each side by 20
20x/20 = 120/2
This is the Answer
