None. The triangle inequality states that the sum of the smaller two sides of a triangle must be greater than the third side. As 4+5=9, this inequality is false in this case, so these sides cannot create a triangle.

Answer:
23°
Step-by-step explanation:
The angle a vector makes relative to the +x axis is found as ...
α = arctan(y/x) = arctan(4.30/10.3) ≈ 22.66°
The angle is about 23°.
__
<em>Additional comment</em>
This vector resides in the first quadrant, so no adjustment of the angle is needed. In other quadrants, 180° may need to be added or subtracted from the angle given by the arctan function to arrive at the correct value. (Some calculators and spreadsheets have an ATAN2(x, y) function that takes signs into account.)
Answer:
1/5 gallon
Step-by-step explanation:
4/5 divided into 4 is the same that 4/5 multiplied by 1/4
4/5* 1/4 = 4/20 = 1/5
Answer:
v =-28
Step-by-step explanation:
-18 - 3 /4 v = 3
Add 18 to each side
-18+18 - 3 /4 v = 3+18
-3/4 v = 21
Multiply each side by -4/3 to isolate v
-4/3 *-3/4v = 21*-4/3
v =-28
