Step-by-step explanation:
Rewrite csc(x) in terms of sin
Multiply the numerator. Notice that the factors in the numerator are reciprocal so they will factor out to 1.
Notice that cotangent and tan are reciprocal so
Step-by-step explanation:
270/90*4 = T

4-2=2
So basically the answer is 2
Harriet works 42 hours a week. She gets paid £9.12 for each hour she works. An estimated amount Harriet gets paid in a week is £378
<h3>How to calculate the percent error?</h3>
Ssuppose the actual value and the estimated values after the measurement are obtained. Then we have:
Error = Actual value - Estimated value
Harriet works 42 hours a week. She gets paid £9.12 for each hour she works.
1 hour = £9.12
Estimated
£9 x 42 hours = 378
Actual
£9.12 x 42 hours = 383.04
