Answer:

<u>x = 8.6 cm</u>

Step-by-step explanation:

To find x, we need to take the sin ratio of the 35° angle.

<u>Identity</u>

  • sin∠x = opposing side length / length of hypotenuse

<u>Solving</u>

  • sin35° = 0.57
  • sin35° = x/15
  • ⇒ x/15 = 0.57
  • ⇒ x = 15 × 0.57
  • ⇒ x = 8.55 cm
  • ⇒ <u>x = 8.6 cm</u>

What is the value of the expression when a = 6, b = 4,and c = 8?
Julli [10]
The answer is: [B]: 3.
______________________________________________
Let us assume that the problem is meant to be written as:
_______________________________________________
  2a / (3b - c) ;

Explanation:
___________________
we are given the values for "a", "b", "c" ; and we are asked to solve the problem when the given values: 
      a = 6, b = 4; and c = 8 .
________________________
Note:
________________________
We have a "numerator" , " 2a " ; and a "denominator" , (3b - c).
_______________________
Let us start by finding the numerator: 
_________________________________
Numerator: 2a = 2*a = 2 * 6 = 12.
_______________________________________
Denominator: 3b - c  = (3*4) - 8 = 12 - 8 = 4
_______________________________________
To solve: Numerator ÷ Denominator = 12 <span>÷ 4 = 3.
_______________________________________
The answer is: [B]: 3.
