Answer:
y = 30
x = 60
Step-by-step explanation:
4y and 2y are consecutive angles, which means they are equal to 180° when added together
that is the same with x and (5x - 180)
to solve, you set the equations to 180
solving:
4y + 2y = 180
6y = 180
y = 30
x + 5x - 180 = 180
6x = 360
x = 60
Answer:
first option
Step-by-step explanation:
Multiplying a complex number by its conjugate gives a real number and thus removes imaginary numbers in the denominator.
If z = a + bi then its conjugate is a - bi and their product
(a + bi)(a - bi) → where a and b are real
= a² + b² ← a real number
