Find the value of x
help please

120

Step-by-step explanation:

Could be wrong but, I think the 40 degrees is equivilent to the angle right below the x, been a while since geometry so forgot what theory or law it's called. But anywas there's a straight line which equals 180 degrees. So 180-40-20 is 120... I dont know if this is right but I feel like it would be the only way to solve it...

120 degrees I think

Step-by-step explanation:

Since the 40 degrees correlates, the line has a value of 20 degrees and 40 degrees making 60 degrees... a straight line is always 180 degrees so 180-60= 120degrees I am pretty sure

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.
