Given that K is greater than 1, B = 2K, a plus the square of C = 2K, AC = the fourth power of K minus 1, what kind of triangle is a triangle with a, B, C as sides

Given that K is greater than 1, B = 2K, a plus the square of C = 2K, AC = the fourth power of K minus 1, what kind of triangle is a triangle with a, B, C as sides

Right triangle a plus the square of C = 2K, the fourth power of AC = k minus 1 will know a-c = 2, and then you can express ABC. Finally, the square of a is equal to the square of B + the square of C

Given that K is greater than, B = 2K, a + C = 2K square, AC = k fourth power-1, then a triangle with a, B, C as sides
A equilateral triangle B obtuse triangle C right triangle

Answer: C
^The sign is power and * is multiplication
It can be seen from the meaning of the title:
(C-a) ^ 2 = （ c+a ) ^ 2 - 4*ac = 4 ；
So B ^ 4 = (C-A) ^ 2 * (c + a) ^ 2, i.e
b ^ 4 = （ c ^ 2 - a ^ 2 ） ^ 2 ;
So B ^ 2 = | C ^ 2 - A ^ 2 |, that is, B ^ 2 = C ^ 2 - A ^ 2, or a ^ 2 - C ^ 2
Either way, it's a right triangle
