What type(s) of symmetry does this figure have?
2 answers:
Answer with explanation:
The given geometrical shape has no, reflectional symmetry,that is ther is no line of reflection when it will,produces mirror image of itself.
And when , rotated in counterclockwise or clockwise direction ,that is a complete revolution,it will appear congruent to itself once,that is after 180 degree revolution in clockwise or counterclockwise direction .So it has rotational symmetry of order 2.

Answer:
The required rate of interest = 14.285%
Step-by-step explanation:
Here, The principal amount = 7,000
The final paid amount = 9,000
Time = 2 years
Let us assume the rate of interest = R
Now, Simple Interest = Amount - Principal
= 9,000 - 7,000 = 2,000
So, the SI on the given principal for 2 years = 2,000
or, R = 14.285%
Hence, the required rate of interest = 14.285%
