<h3>Answer: 416 cubic mm</h3>
Work Shown:
V = lwh
V = 10.4*5*8
V = 416
Explanation: We multiply the length, width, and height to get the volume of the block. The units for the volume are in cubic millimeters which can be written as "cubic mm" or to mean that we're cubing all of "mm", and not just a single m.
I guess you could say to be very clear that both "m"s are being cubed, though this convention isn't something I've seen a lot.

The line y = mx + c has a slope of m.
Parallel line:
A parallel line will also have a slope of m, and should be of the form
y = mx + k
Because the line passes through the point (a,b), therefore
ma + k = b
k = b - ma
The equation of a parallel line is
y = mx + b - ma
= m(x-a) + b
Perpendicular line:
A perpendicular line will have a slope of -1/m, because the product of slopes should be -1.
The equation for a perpendicular line is of the form
y = -(1/m)x + k
Because the line passes through (a,b), therefore
-(1/m)a + k = b
k = b + a/m
The equation for a perpendicular line is
y = -(x/m) + b + a/m
= -(1/m)(x-a) + b

Answer:
x = 1.5
Step-by-step explanation:
using the sine ratio in the right triangle and the exact value
sin60° = , then
sin60° = =
=
( cross- multiply )
2x = 3 ( divide both sides by 2 )
x = 1.5
