Answer:
see explanation
Step-by-step explanation:
(1)
The sum of the 3 angles in a triangle = 180° , thus
a + b + c = 180
(2)
adjacent angles are supplementary, thus
b + d = 180
(3)
From (1) and (2)
b + d = a + b + c ( subtract b from both sides )
d = a + c
Answer:
You move the -5 to the other side.
Answer:Okay
Step-by-step explanation:
The correct option is (2)
For any quadratic equation: ax2 + bx + c = 0.
The complex roots are expressed in the form a ± bi.
where a is the real part
& b is the imaginary part.
Since, one root is √7 + 5i, therefore the other root will be of the form <span>√7 - 5i.
Hence, option (2) is correct.</span>
