Answer:
The number of unique rhombuses that can be constructed is one.
Step-by-step explanation:
A rhombus is a 2D shape with 4 straight sides that are all equal length. Also opposite sides are parallel and opposite angles are equal.
The addition of the 4 angles in a rhombus is equal to 360°. We know that one angle is 40°, its opposite angle is also 40°, then the addition of the other 2 angles (which are equal) is 360° - 2*40° = 280°. The other 2 congruent angles measure 140°.
If you have the length of one side (8 cm in this case), you have the length of all sides.
In conclusion, with one side and one angle a rhombus is completely defined and it's unique.
All the 5 angles are equal to 286, so....
360 - 286 = 74
then,
180 aka a straight line
180 - 74 = 106
interior is 74
exterior is 106
Answer:
<h3>37.5m/s</h3>
Step-by-step explanation:
If a coal train in Montana starts from rest and accelerates at 2.5 m/s2 for 15s,let us calculate the final velocity of the train.
Use the equation of motion v = u + at where;
v is the final velocity
u is the initial velocity = 0m/s (starts from rest)
a is the acceleration = 2.5m/s²
t is the time = 15secs
Substituting the given parameters into the formula;
v = 0+(2.5)(15)
v = 0+37.5
v = 37.5m/s
Hence the final velocity of the train is 37.5m/s
