Hello there!
x + (2x + 40) + (3x - 50) = 15002
Remove the parentheses
x + 2x + 40 + 3x - 50 = 15002
Combine like terms
x + 2x + 3x + 40 - 50 = 15002
6x - 10 = 15002
6x = 15002 + 10
6x = 15012
x = 15012/6
x = 2502
As always, it is my pleasure to help students like you!
I need a diagram to answer
For the three basic trig identities (sin, cos, tan) there are three more which act as their reciprocals (csc, sec, and cot respectively)
A reciprocal of x can be represented as 1/x.
Therefore, cscӨ can also be represented as the reciprocal of sinӨ...1/sinӨ.
In that case, our answer should always be true so long as we put in a real number for theta, because that's the domain of sinӨ, right? However, we also have to satisfy the domain of cscӨ, and the limitations become extremely obvious when you look at this reciprocal identity equation...sinӨ cannot be zero because it is impposible to divide by zero! Looking at the unit circle, any multiple of π will make sin<span>Ө = 0, so there's your answer.
D. All real numbers except multiples of pi</span><span>
