Angle B: 81° .
____________________________________
Angle C: 99° .
____________________________________
Angle D: 81° .
_____________________________________________
Explanation:
_______________________________________________________
Angle B:
_______________________________________________________
Given: m∡A = 99° ;
∡A and ∡B are "supplementary angles" ;
and supplementary angles add up to 180°.
_______________________________________________________
→ So, m∡B = 180 − 99 = 81° .
_______________________________________________________
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° .

Answer:
Step-by-step explanation:
From the given figure, it can be seen that , thus ΔABC is an isosceles triangle.
Therefore,
⇒
Solving the above equation, we get
⇒
⇒
⇒
Now, substituting the value of x in AC, we have
⇒
⇒
⇒
⇒
Thus, the length of the side AC of the given triangle is 25 units.
