Answer:
Step-by-step explanation:
1) Sin² Ф = 1 - cos² Ф
So, 1 - Sin² Ф = 1 - (1 - cos² Ф)
= 1 - 1 + cos² Ф = cos² Ф
2) tan x = Sin x /Cos x
tan x * csc x = Sin x /Cos x * 1/Sin x = Sinx * 1 / cos x * sin x
=1/cos x = Sec x
Answer:
∠2=92°
Step-by-step explanation:
Using an angle formula, -8x+144=2x+74
Simplification:
-8x+144=2x+74
-8x+70=2x
70=10x
x=7
Therefore, each angle is 88°
Now, because ∠2 is adjacent to one of 88°, they add up to 180°
Therefore,
180°=88°+∠2
∠2=92°
Answer:
The slope is - 3/5
Step-by-step explanation:
You move up 3 and over 5
Rise over run, so 3 over 5
Since you move left, it's negative
3/5 can't be reduced
We will have that the only graph that could represent the heigth of a rocket is graph A. Assuming that the x-axis represents the ground, then after some time it will go back to it.
