Rewriting the left hand side,
csc²t - cost sec t
= (1/sin²t)-(cost)(1/cost)
= 1/sin²t - 1
= 1/sin²t - sin²t/sin²t
= (1-sin²t)/sin²t
= cos²t/sin²t
= cot²t
178+63+37=278 So if we were ESTIMATING it would be around 280.
I hope that this helps!
Answer:
a)true becuase ×1/2 and ÷2 are doing the same thing
b) true bc they simplified the equation
c)true bc a term is a number or letter and 1/2 is the coefficient
d) true bc thats what the equation is telling you to do

1045 = 1000 since 45 is not near 2000
6589 = 7000
Near to low: 0, 1, 2, 3, 4
Nearer to High: 5, 6, 7, 8, 9
