Sin(42) = cos(x)
Solve for x

X = 48

Step-by-step explanation:

When you type sin(42) in your calculator it will give you something around 0.669.

If you try reverse sinus sin-1(0.669) it will give you 42.

Therefore you can say that:

Cos(x) = 0.669

So you can reverse the cos to get your answer

Cos-1(0.669) = 48

Or

Cos-1 (sin(42))

sorry i dont know my friend

a reflection across the x-axis , followed by the by a reflection across the y-axis , and then a scale dilation of 0.5 .
