Answer:
First blank is cos(h)cos(x)
Second blank is sin(x)
Step-by-step explanation:
Look up the identity and apply it here
from all the 247 students, 7 went on by cars, meaning they didn't fit in the buses, so they students that went in the buses are 247 - 7 = 240.
now, we know there were 6 buses, so dividing 240 evenly by 6, 240/6 = 40.
Answer:
That's incorrect. The simplest way to show this is by evaluating the functions at a given point. Let's say x=0, then:
Sin(-x) = Sin(0) = 0
-cos x = -cos (0) = -1
Therefore, Sin(-x)≠-cos x.
Answer:
x=145
Step-by-step explanation:
simply subtract 35 from both sides, so you can isolate the variable. once done, you will get that x=145
