2 is the slope so the slope perpendicular to that is -1/2 (negative reciprocal)
-5=-1/2(9) 9*-1/2=-4.5 and -4.5 - 0.5 = -5 so the equation for the line is y=-1/2x -0.5
To find the volume, multiply length, width, and height together
19 x 20.4 x 6 = 2325.6
2325.6 in³ is your answer

Factor out the GCF first
3(2x² - x - 10)
3(2x - 5)(x + 2)
Hello.
In your question, we can see that the points Q, P, and R can be assumed that they are in a straight line, meaning that the angle measures will add up to 180 (think of half a circle, which is 360 degrees).
This means that every angle added up will add up to 180 degrees.
Meaning we can set up the below equation:





After finding
, we can plug it back in to each expression for each angle measure.
∠QPS = 
∠SPT = 
∠TPR = 
Hope this helps!
