Answer:
Other integer = -5
Step-by-step explanation:
Let the integers be x and y
Product of x and y = 45.
Given one of the integer = -9 . Let y = -9.
Therefore,
Answer:
Step-by-step explanation:
Remark
The way this is worded, it sounds like it is a horizontal distance. However by the marking it looks like they want the hypotenuse. Life can be very confusing sometimes.
The angle of the triangle that you need to know is the one on the right. The line of sight line is parallel to the base of the triangle. So the angle on the right is 8 degrees by the Z theorem.
Solution
Sin(8) = 1817 / x Multiply both sides by x
x*sin(8) = 1817 Divide by sin(8)
x = 1817/sin(8)
sin(8) = 0.1392
x = 1817/0.1392
x = 13055.7
Note
Watch how you do this. I would put it into your calculator as
1817
÷
sin(8)
=
If you use the rounded answer I gave for sin(8), you might get it wrong. This is a big distance and you should just use the exact number you get for sin(8).
Answer:
the roads are skew
Step-by-step explanation:
North and south is <u>not</u> parallel to east and west. If the roads were in the same plane (not separated vertically), they would be perpendicular. Since they do not intersect and they are not parallel, they are <em>skew</em>.
