Prove the following identities. (Remember, you may only change one side of the equation)

(a) Sec θ (1 - sin^2 θ) = cos θ (b) 1 = 1 + sin x/ sin x - csc x

Step-by-step explanation:

answer: 1,380

step-by-step explanation:

1: you turn %15 into a decimal by moving the decimal point two places to the left.

2: and then you multiply .15 by 1,200 , which will get you 180.00

3: from there you will add 180 to 1,200

4: which will get you 1,380

hope it *im kind of slow so idk if my answer is right*

72 is the answer to this problem
