Condense z₁ and z₂ into their exponential forms:
z₁ = 3 (cos(π/4) + i sin(π/4)) = 3 exp(i π/4)
z₂ = 7 (cos(3π/8) + i sin(3π/8)) = 7 exp(i 3π/8)
Then the quotient of z₁ and z₂ is
z₁ / z₂ = 3/7 exp(i (π/4 - 3π/8)) = 3/7 exp(-i π/8)
and in trigonometric form,
z₁ / z₂ = 3/7 (cos(-π/8) + i sin(-π/8))) … … … D
Refer to the image that I attached to my answer.
According to the graphing calculator, the two equations have two points of intersections (the points where the different colored lines cross).

The measure of angle E is 75°.
Solution:
Given data:
∠E = 5x, ∠F = 7x – 13 and ∠R = –2 + 6x
A quadrilateral inscribed in a circle is called cyclic quadrilateral.
∠R and ∠G are opposite angles in a cyclic quadrilateral.
<em>In cyclic quadrilateral, opposite angles are supplementary.
</em>
⇒ m∠R + m∠F = 180
⇒ –2 + 6x + 7x – 13 = 180
⇒ 13x – 15 = 180
Add 15 from both sides of the equation, we get
⇒ 13x = 195
Divide by 13 from both sides of the equation, we get
⇒ x = 15
<u>To find the measure of angle E:</u>
m∠E = 5x
m∠E = 5(15)
m∠E = 75
The measure of angle E is 75°.
