Answer:
x ≈ 18.9
Step-by-step explanation:
using the cosine ratio in the right triangle
cos19° = 
= 
( multiply both sides by 20 )
20 × cos19° = x , then
x ≈ 18.9 ( to the nearest tenth )
I think it’s 18 and I will explain how I got that
Explanation: so first I added all the marbles she took out to see the total she took out which was 50 and if she did it 90 times I need to see how much time 50 she did it more and that was so 90 divided by 50 is 1.8 and that times 10 (times because we want to see how many times the red marble would come out) and that’s 18
The slope is 15, if that's what you're asking for.
y-int is 50.
Four hundred fourty-four plus two hundred twenty two is six hundred sixty-six
