The other expression that has a value of  is A) sin B.
 is A) sin B.
Step-by-step explanation:
Step 1:
 
  
 
For angle B, the opposite side measures 7 units, the adjacent side measures 24 units and the hypotenuse measures 25 units.
 
  
 
Step 2:
For angle A, the opposite side measures 24 units, the adjacent side measures 7 units and the hypotenuse measures 25 units.
  
 
Step 3:
tan C cannot be determined as C is the right angle. The opposite side and hypotenuse of the triangle would be the same.
So sin B also has a value of  This is option A.
 This is option A.
