Answer:
Left diagram cos(y) = 0.6
Right diagram x = 5 makes the equation true.
Step-by-step explanation:
Left diagram
Both the sin(x) and the Cos(y) use the same side as the non hypotenuse side.
Therefore they most be equal.
So if sin(x) = 0.6, then cos(y) = 0.6
=========================
Right diagram
You can factor this to get the answer.
From the first 2 terms, take out x^2. From terms 3 and 4 take out 2.
x^2(x - 5) + 2(x - 5) = 0
Take out the common factor of (x - 5)
(x^2 +2)(x - 5)
x^2 + 2 yields a complex answer (which doesn't matter for this question)
x - 5 = 0
x = 5
