Answer:
cos(X+Y) = cos(55+35) = cos(90) = 0
Step-by-step explanation:
cos(X+Y) = cosXcosY - sinXsinY
cos(55+35) = cos(55)cos(35) - sin(55)sin(35)
cos(55+35) = cos(55)cos(35) - cos(90-55)cos(90-35)
cos(55+35) = cos(55)cos(35) - cos(35)cos(55)
cos(55+35) = 0
cos(90) = 0

Answer:
25 ft
Step-by-step explanation:
V = AH, where A = area of the base, and H = height (length) of the prism
A = bh/2 for a triangle
V = bh/2 × H
2500 = (10)(20)/2 × H
2500 = 100H
H = 25
