Triangle angle theorems the value of x is?

what you do I set 45x equal to your two other angles since the sum of those two angles is equal to that angle outside the triangle.

so you have

45x=57+x+25x

combine like terms

45x=57+26x

then subtract 26x on both sides to get

19x=57

lastly divide by 19

x=3

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.

the 3rd on is correct
