Secd(38) = 1/cosd(38) = 1/sqrt[1-sind^2(38)] because cos^2(x) + sin^2(x) = 1 cos(30) = sqrt(3)/2 = 0.8660 cos(45) = 0.707 so cos(38) can be assumed to some where around 0.8 = 1/0.8 = 1.25
Therefore D is correct answer
Answer from: Quest
the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.
hope this ! ^w^

Where the white dots are is where your points should be plotted.a translation is simply just moving something from one place to another. in this case, you would move each plot point of the original shape 2 units up, and 5 units to the left.
