There are no such numbers in real numbers.
Do you perhaps want a solution in complex numbers?
Answer:
4 sqrt(2) =c
Step-by-step explanation:
The base is the triangle
We can use the Pythagorean theorem to solve
a^2 + b^2 =c^2 where a and b are the legs and c is the hypotenuse
4^2 + 4^2 = c^2
2 * 4^2 = c^2
Take the square root of each side
sqrt(2 * 4^2) = sqrt(c^2)
sqrt(2) *sqrt( 4^2) = c
4 sqrt(2) =c
The reciprocal of seven (7) would be 0.142857143
Answer: 20
Step-by-step explanation:
numbers belonging to the figure on the left are 2.5 times less than on the right so to find x multiply 8 by 2.5 and that is 20
