Answer:

A.

Step-by-step explanation:

as u can see,the other acute angle is 43° and the other is also an acute angle and acute angles must not surpass until 80° meaning, the other acute angle is 47°

Given,

  • A right angle that means 90°.

  • One angle is 43°

Now,

[tex] \angle \: ACB = 43 \degree + \angle \:BCD [/tex]

=> 90° = 43° + BCD

=> BCD = 90° - 43°

=> BCD = 47°

Option ( A ) 47° is correct answer
