Answer:
b = 
Step-by-step explanation:
Since the triangle is a right angled triangle, the appropriate trigonometric function can be applied to determine the value of b.
Thus, to determine the value of b;
Sin θ = 
Sin b = 
= 
= 0.38462
⇒ b =
0.38462
= 22.6202
b = 
The measure of angle E (= b) is
.
=
Answer:
B he used the incorrect formula for the volume of the prism
The correct answer is B) $50 per hour. Hope this helps!
Okay so you are correct with the gradient of the perpendicular line it is -5/2 however the equation is not y= -5/2 -1 because it is a new Line and has a new y-intercept therefore its Y=-5/2 + C but you have corrected that when doing the formula and have got the right answer
