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.
Answer:
6.32 feets
Step-by-step explanation:
Given that:
Height of ramp = 2 feets
Length of base = 6 feets
Length of ramp = l
Using Pythagoras rule :
Hypotenus = sqrt(opposite² + adjacent²)
Length of ramp = sqrt(height of ramp² + length of base²)
l = sqrt(2² + 6²)
l = sqrt(4 + 36)
l = sqrt(40)
l = 6.3245
Length of ramp = 6.32 feets
Answer:
Option B, c and e are the correct
Answer:
From the above image when the input of f(x) is 9 the output is 1
So f^-1(1) is just the reverse when the input is 1 the output is 9
So f^-1(1) = 9
Hope this helps
6+ 4×whatever y equals +9
