It's B since sin is opposite divided by hypotenuse, so find the hypotenuse by using pythag therom and you will get 25, divide opposite of angle C which is 24 by hypotenuse which is 25
The answer is that his average is 75.5 for the second nine weeks
Answer:
Given lines are PERPENDICULAR to each other.
Step-by-step explanation:
We have the equations,
and 
The slope-intercept form of a straight line is 'y=mx+b', where m is the slope and b is the y-intercept.
So, accordingly we get that,
The given equations have slopes
and
.
As we see that, 
Thus, the product of the slopes of the given lines is -1.
Hence, the given lines are PERPENDICULAR to each other.
The answer is 135 degrees as 45 add 135 equals 180 degrees as it's a straight line
