Cos60° = 0.5
Any angle less than 90° is an acute angle.
Therefore, 60° is the acute angle.
Dannng I thought I seen this one before
Hello there again. I have your answer: Solve for x by simplifying both sides of the equation, then isolating the variable. x = −8
Answer:
x ≥ -5
Step-by-step explanation:
If we have a translation to left c units, we write " x + c " in the function, and
If we have a translation to right c units, we write " x - c" in the function
If we have vertical translation up b units, we "add b to the function", and
If we have vertical translation down b units, we "subtract b to the function"
The parent function is 
Since translation left 5 units and up 3 units, we can write:

The domain is affected by the square root sign and we know the number under the square root CANNOT be negative, so we can say:
x + 5 ≥ 0
x ≥ -5
This is the domain.
