Answer:

<h2>The time is 6.1 seconds, approximately.</h2>

Step-by-step explanation:

The given function is

d=4.9t^{2}

Where d is distance in meters and t is time in seconds.

Let's isolate t

\frac{d}{4.9}=t^{2}\\  t=\sqrt{\frac{d}{4.9} }

Where d=185 \ m

t=\sqrt{\frac{185}{4.9} } \approx 6.1 \ sec

Therefore, the right answer is C. The time is 6.1 seconds, approximately.

Which postulate or theorem proves that these two triangles are congruent?
Alla [95]

AAS congruence theorem.


We know that <H is congruent to <F and <GJH is congruent to <JGF.

We also know that JG is congruent to JG, which gives us a side and two angles, so AAS would prove them congruent.
