It should be B because i did it in paper
For simplicity, disregard the fractions. Then you have 48 + (- 39), since opposite signs change into a negative sign, you have 48 - 39. What is the answer?
POSITIVE
I found the answer to 5, but I couldn't see the rest of worksheet to solve 6 thoroughly.
Both of these problems can be solved through substitution using the variables that you know equal a number.
For example #5: 5(3)(3)-7(3)+4
45-21= 24, and 24+8=28
That is how you solve number 5 and can also solve 6 the same way using the same method.
Complementary angles have a submission of 90 degrees thus :
Collect like terms
Add both sides 36
Divide both sides by 8

Now let's find the measure of A :
And we're done...
Don't have a good day , Have a great day ♡
We know that cot = cos/sin
then cot^3 = cos^3 / sin ^3
we also know that csc = 1/sin
then 1/csc = sin
cot^3t/csct
=(cos^3t / sin^3t) * sint
=cos^3t / sin^2t
1+cot^2 = csc^2
csc^2 -1 = cot^2
cost(csc^2t-1)
=cost(cot^2t)
cost( cos^2t/sin^2t)
=cos^3t/sin^2t
It implies that both sides are equal
hope it helps
