2 false
3 false
4 true
Answer:
Step-by-step explanation:
The diagram is given to you below. I could not change <C so that it was theta. So C = theta.
So C is the reference angle. Call it theta when you think of it. The diagram shows you how cos(C) must be set up.
The adjacent side is 7
The hypotenuse is 18
theta = C = cos-1(7/18) = 67.11
To the nearest degree 67.11 = 67
Round 57.8 to 60 and round 81 to 80.
60/80 or, if you simplify it, 3/4
And it is common knowledge that 3/4 = .75
So the quotient of 57.8/81 is ~.75
