Answer:
Option (4) is correct.
Step-by-step explanation:
We need to show that
is equivalent to radical
.
We can do it as follows :

Hence, the correct option is (4).
PQRS is corresponding to LMNO.
Which means that angle QRS is corresponding to angle MNO
Hello!
This equation shows that ΔABC is approximately equal to to ΔDEF. This means that the angles are the same. We will subtract both angles from 180 to find m∠F.
180-76-56=45.
Therefore our answer is D) 45°.
I hope this helps!
