First you should subtract the first numbers. 82-33=49 Next, you need to subtract 49- the product, which is 49-35=14 Finally, check your work. 82-14-33=35
a) 45° cause tan = sin/cos and sin 45 and cos 45 both give square root 2/2
b) 120°
c) sin = -1/2 = -30° or 330° both are same
Use the trig circle which i have included in the answer to better understand trig angles
hope that answers your question
I want to let you know that each angle has sets of coordinates the left number is cos and right is sin. Ex) sin of 30 is 1/2 and cos of 30 is square root 3/2 In case you dont fully understand dont hesitate to comment.
During an emergency exercise, a submarine dives 37 ft, rises 16 ft, and
then dives 18 ft. The net change in the submarine's position = - 37 + 16 - 18
Net change is the difference between a security's closing price for a given trading period and its closing price for the current trading session. The term "net change" for stock prices often refers to a daily time frame, therefore the net change for the specific day in question might be either positive or negative.
Therefore, the net change = -39 ft.
What is a net change?
Net change is the difference between the quantity of a variable at the end state and the starting state.
For example, start with some number. Add 10 to it, subtract 5 from it, again add 7, then subtract 16.
The net change will be 10 + 5 + 7 - 16 = 6
Whatever number you have started with, the result is 6 more.
