Answer:

Step-by-step explanation:
We want to write the trignometric expression:

As an algebraic equation.
First, we can focus on the inner expression. Let θ equal the expression:

Take the secant of both sides:

Since secant is the ratio of the hypotenuse side to the adjacent side, this means that the opposite side is:

By substitutition:

Using an double-angle identity:

We know that the opposite side is √(u² -100), the adjacent side is 10, and the hypotenuse is u. Therefore:

Simplify. Therefore:

I think it’s the second option
88=2(4b+6)-4
88=8b+12-4
88=8b+8
-8 -8
80=8b
80/8=10b
Answer:
You spend $180 on pants and shirts. You pay $12 per pair of pants (x) and $15 per shirt (y). You buy 6 more pairs of pants
Answer:
15=a
Step-by-step explanation:
how I got this is because a triangle is equal to 180 so you have to add all of the things together then you get 12a=180 the reason why I got this is because if you add it so 6x+3a-1+3a+1 so you add common terms then you will equal to 12a then you divide it on both sides so then you equal to 15
