<span>
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° .
