Answer: 
=========================================================
Explanation:
Use the pythagorean trig identity 
and plug in the fact that 
Isolating sine leads to 
. I'm skipping the steps here, but let me know if you need to see them.
The result is negative because we're in quadrant 4, when y < 0 so it's when sine is negative.
Therefore,
The correct answer would be a length of 12 meters long
Answer:
i dont know how to do math slthough i need the points k bye :)
Step-by-step explanation:
teehee. finnesed yo as$
Given that Z is the centroid of a triangle RST. This means that Z is the point of intersection of the three medians of the triangle.
So,W is the midpoint of RSV is the midpoint of RTWe are given that:RV = 4x + 3 and VT = 2x + 9
Since V is the midpoint, then:RV = VT4x + 3 = 2x + 94x - 2x = 9 - 32x = 6x = 3
Now put the value of x in WS = 5x-1WS = 5x-1WS = 5(3) - 1 WS = 15 - 1 = 14WS = 14
Since W is the midpoint of RS, therefore RW = WSand WS = 14Therefore:
RW = 14
Answer:
x=3 ??i think
Step-by-step explanation:
cuz it makes sense like that
