Use the sine:

$sine=\dfrac{opposite}{hypotenuse}$

$\sin18^o=\dfrac{x}{85}\\\\\sin18^o\approx0.309\\\\\dfrac{x}{85}=0.309\ \ \ \ |\cdot85\\\\\boxed{x=26.265\approx26.3}$

<h3>Answer: 26.3</h3>

Answer:

SSS

Step-by-step explanation:

I can identify that these triangles are congruent by using the SSS (Side, Side, Side) postulate theorem. I know this because first, second, and home triangle share the same side as the third, second, and home triangle, meaning they are congruent, so are the other sides of the angle since the question states they are congruent.
