Yes
tan=oposite side/adjacent side
when the oposite side=the adjacent side, then we can have tan function equal to 1
that hapens in a 45-45-90 triangle
that is when you have tan(45°) or
An example of this may be:
Split up the middle term into factors of -6.
Group like terms together.
Thus, x = -6 and x = 1
You simply do the direct substitution,
you remove m and put the number of months given,
b=540-(30*9)= 270$
This example gives you an equation where calculates how much your balance is, an equation of b (balance) as a function of m (number of months), so simply substitute with the number of months given to you into the equation and you get the answer.
Hope this helps.

Answer: Telescopes use lenses or mirrors to collect and focus waves from the electromagnetic spectrum, including visible light, allowing us to look at celestial objects. By studying the electromagnetic waves given off by objects such as stars, galaxies, and black holes, astronomers can better understand the universe.
