Answer:
B. 60cm^3
Step-by-step explanation:
The volume of a right triangular prism is
V = BH where B is the area of the triangle and H is height
B = 1/2 bh where b =5 and h =8
B = 1/2 *40 = 20
V = (20) * 3
V = 60 cm^3
We need to be careful to do the area of the triangle first

AWESOME QUESTION!!!
2)) answer is 73
4)) answer is 5(x + 2)
Answer:
Step-by-step explanation:
4.
2ab cos C=a²+b²-c²
2×31×14 cos C=31²+14²-40²
868 cos C=961+196-1600=-443
cos C=-443/868
C=cos^{-1}(-443/868)≈120.688≈120.69°
5.
by sine formula
m∠B=180-(62+55)=180-117=63°

no because the absolute value of 1/4 is 1/4 and the absolute value of -4 is 4
absolute value is just a positive version of the number inside of the symbol
