Answer:

Step-by-step explanation:
Solving for x:

In this form is easy to identify the factors of the quadratic function:
. The two solutions are the values that make each of the factors equals to zero.

Sec θ = 3
1/cos θ = 3
cos θ = 1/3
csc (90 - θ) = 1/sin (90 - θ) = 1/cos θ = 1/(1/3) = 3
Therefore, csc (90 - θ) = 3.
Hi!
Let's just take this part by part.
The sum of seven is the first part written. You can deduce from that, that it's 7 + something.
The next part is the quotient of a number x and 8. A quotient is the result of something being divided, so we can figure out that it's x / 8.
Putting it all together, you get the expression as 7 + x / 8.
Hope this helped!
