How to do the problem:
Assuming that you mean you want 12% of the number 80 and showing work, here is the answer:
To get X percent of any number, write the percent as a decimal and then multiply that decimal by the whole.
What I mean:
You want 12% of 80
so first change 12% into a decimal
12% is equal to .12 as a decimal
Then multiply that decimal by the whole
Since you want 12% of 80, 80 is the whole
that means you do .12 * 80
which is equal to 9.6
<u>Thus(answer)</u>
12% of 80 = 9.6

Answer:


Step-by-step explanation:
To solve this question we're going to use trigonometric identities and good ol' Pythagoras theorem.
a) Firstly, sec(θ)=52. we're gonna convert this to cos(θ) using:

we can substitute the value of sec(θ) in this equation:

and solve for for cos(θ)

side note: just to confirm we can find the value of θ and verify that is indeed an acute angle by
b) since right triangle is mentioned in the question. We can use:

we know the value of cos(θ)=1\52. and by comparing the two. we can say that:
- length of the adjacent side = 1
- length of the hypotenuse = 52
we can find the third side using the Pythagoras theorem.




- length of the opposite side = √(2703) ≈ 51.9904
we can find the sin(θ) using this side:


and since
