Angle B:</span>
_______________________________________________________
Given: m∡A = 99° ;
∡A and ∡B are "supplementary angles" ;
and supplementary angles add up to 180°.
_______________________________________________________
<span> → So, m∡B = 180 − 99 = 81° </span>.

Angle C: 99° .
_______________________________________________________
Explanation:
_______________________________________________________
Given: m∡A = 99° .
∡A and ∡C are "vertical angles". Vertical angles are congruent.
______________________________________________________
→ So m∡A = m∡C = 99° .
______________________________________________________
Angle D: 81° .
______________________________________________________
Explanation:
______________________________________________________
∡B and ∡D are vertical angles. Vertical angles are congruent.
As previously determined above, m∡B = 81° .
______________________________________________________
→ So, m∡D = m∡B = 81° .

Solution:
Given: zj = 3- j2, zz = - 4 + j3
Part a:
zj = 3- j2 = 
zz = - 4 + j3 = 
Part b:
|zj| = |3− j2| = √3² +(−2)² = √13 = 3.60
|z1| = √(3− j2)(3+ j2) = √
13 = 3.60.
Part c:
With the help of part a:
z1z2 = 
Area of rectangle is equal to: length times width. A=l•w
If A=24cm^2
24cm^2=1cm•24cm
24cm^2=2cm•12cm
24cm^2=3cm•8cm
24cm^2=4cm•6cm
Good luck
