Answer:
B. Multiplication or Division property of equality
Step-by-step explanation:
Both sides of the equation have been multiplied by -1. The multiplication property of equality tells you that multiplying both sides of the equation by the same number does not change the truth of the equation (and the variables retain their values).
Answer:
tanx = 1
Step-by-step explanation:
I assume you mean sinx = cosx
In this case we have to recognize that tanx = sinx / cosx
So if we divide cosx over we can get tanx
So:
Cosx divided by itself gives us 1
sinx / cosx = 1
tanx = 1
sorry but can u post a better picture i cant really help if the picture isn’t good
Answer:
