Answer:
C
Step-by-step explanation:
Volume of rectangular prism = length * width * height
Volume of triangular prism =( length * height * base )/2
Given,
Volume of rectangular prism = 18 + volume of triangular prism

18x = 18+14x
4x=18
x= 4.5 ft
So volume of rectangular prism = 6* 4.5* 3 = 81 ft³
Volume of triangular prism = (7* 4.5 * 4) / 2 = 63 ft³
If we are to connect both tips of the cliff to the approaching ship, we form a right triangle. The height of the cliff is the opposite side of the angle of depression. The trigonometric function that would allow us to solve for the distance is tangent.
tan 18.2° = opposite /adjacent = 426 ft/ x ft
The value of x from the equation is 1295.68 ft
Thus, the answer is the second choice.
Answer:
X = 50
Step-by-step explanation:
2x-x = 40 + 10
X =50
Take the x to be on the same sides and the normal numbers in the other side. Then work them out.
