Answer:
<em>Value of x = 25</em>
Step-by-Step Explanation:
~ Knowing that, in a right triangle ~
sin(40-x)=cos(3x) ⇒
sin(40-x)=sin(90-3x) ⇒
40 - x = 90 - 3x ⇒
40 - x +3x=90 - 3x +3x =>
40+2x=90 =>
2x=50 =>
x = 25
<em>Now it is proven to be that,</em>
<em>x = 25</em>
If you were to solve it, your answer would be A) 4.
