-20 + y = 2
y = 22
20 + 3y = 6
y = 14/3
Answer:
Cosy° = 
Step-by-step explanation:
From the picture attached,
By applying all trigonometric ratios in the given right triangle,
Siny° =
= 
tany° =
= 
Therefore, Cosy° = 
Cosy° = 
Therefore, Cosy° =
will be the answer.
There are no values of x that make the inequality true
No solution.
