Answer:
Since this is a right triangle with one angle and hypotenuse given and opposite side unknown, we can use the definition of sine to find the unknown side.
sin 17 = x/hypotenuse = x/19
x = 19sin17 = 5.6
19x-15 = 15x -7
4x = 8
x =2
19(2) -15 = 23
15(2) -7 = 23
gaira ALSO multiplied 6 by x, when 6 doesnt have 6x.
so the correct answer would be only -3.8(-7.5) + 6 which is 34.5.

Answer: D.-6 and F.3
Step-by-step explanation:
The given rational number : 
To find : The value of x , where the rational expression becomes equal zero.
Let's check all the options :
A. 7
At x= 7 , 
B. -7
At x= 7 , 
C. 6
At x= 6 , 
D. -6
At x= -6 , 
E. -3
At x= -3 , 
F. 3
At x= 3 , 
Thus, at x= -6 and 3 , the rational expression equals to zero .
So , the correct options are : D.-6 and F.3
