<span>A function that repeats its values at regular intervals is called a periodic function</span>
A^2 + b^2 + c^2 - ab - bc - ca = 0
a.a + b.b + c.c = a.b + b.c + c.a
equating term by term:-
a = b
b = c
c = a
Therefore a = b = c
Answer: X=136 degrees
Explanation: A triangle has a total of 180 degrees measuring all 3 angles. 180-90-46 gives me 44 left, then subtract 44 from 180 and that gives you 136 degrees.
You can just do the inverse operation. 39 divied by 10 = 3.9
so 3.9 *10 =39
hope it helped
