Answer:

30°

Step-by-step explanation:

knowing that the sum of the inner angles of a triangle is 180° , so we got the two angles (102° & 48°), so we add them then subtract it from 180°

180°-(102°+48°)=x

180°-150°=30°

x=30°

The correct answer is:  [B]:  " 9.6 cm " . 
____________________________________________________________

Explanation:
____________________________________________________________

Let "FH"  = "x" ;  for which we wish to solve.

45 cm / 12 cm = 36 cm  /  "x" (in "cm") ; 

To solve for "x" ;  
 
Cross--multiply:

Note:    Given:   

" \frac{a}{b} =  \frac{c}{d} " ;  " ad = bc " ;  (b ≠ 0 ; d ≠ 0) ; 


So:  " 45x = 12 * 36 "   ; 

→  45x =  432 ; 

Divide each side of the equation by "45" ; 
     to isolate "x" on one side of the equation; & to solve for "x" ; 
 
→  45x / 45 = 432 / 45 ; 

→  x = 9.6 cm ; 
___________________________________________________________
→  which corresponds with:  
___________________________________________________________

→  Answer choice:  [B]:  " 9.6 cm " .
