Answer:

Step-by-step explanation:

we need that theta angle .. soooo.... use SOH CAH TOA to remind yourself how the trig functions fit on the triangle.....

since we have all 3 side any one of the above trig functions would work. as a side note.. Tan is limited to the 1st quadrant on a calculator.. so maybe Cos is a good choice. although it would work in this case....

sooo ....

Cos(Ф) = Adj / Hyp

Ф = arcCos( 24 /25)

Ф ≈16.26°

I don't have csc on my calculator but I know that 1/sin = csc sooo

csc(16.26)=1/sin(16.26) ≈ 3.57

sec(16.26)= 1/cos(26.26) ≈ 1.041

cot(16.26) = cos(16.26) / sin(16.26) ≈3.476

Solve the inequality algebraically. Write the solution in interval notation.<br> |9x + 10| < 15

viva [34]

The given inequality is

$| 9x+ 10 |$

First we need to remove the absolute sign , and when we do so , we will get a compound inequality, that is

$-15< 9x+10 < 15$

To solve for x, first we need to get rid of 10. and for that, we have to do subtraction

$-15-10$

Now we need to get rid of 9, and for that, we do division

$\frac{-25}{9}< x< \frac{5}{9}$

So the required solution is

$( \frac{-25}{9} , \frac{5}{9})$
