Answer:
Option A 
Step-by-step explanation:
we know that
To divide complex numbers, you must multiply by the conjugate.
we have

To find the conjugate, change the sign between the two terms in the denominator
so

Step-by-step explanation:
The long leg and the hypotenuse of the isosceles right triangle will be 7.07 units.
<h3>What is a Pythagoras theorem?</h3>
The Pythagoras theorem states that the sum of two squares equals the squared of the longest side.
The Pythagoras theorem formula is given as
H² = P² + B²
The short leg of a 90-45-45 triangle is 5.
The right triangle is an isosceles right triangle. Then the two side will be same.
Then the long leg and the hypotenuse will be
H² = 5² + 5²
H² = 25 + 25
H² = 50
H = 7.07 units

After this step, find the button on your calculator that says 'tan' and type n 30 degrees, then press enter or the equal sign or whatever button you press to calculate.
You should get that tan(30) = 0.5774
Now plug that back into the equation
(approximated)
Hope that helps!
