Using a trigonometric equation, it is found that it will take 2.28 minutes until the two trains are first equidistant from the child.
<h3>What is the distance of each train to the child?</h3>
The distance of the first train is:
The distance of the second train is:
<h3>When are the trains equidistant to the child?</h3>
When 
, hence:
The following substitution is made:
Hence:
Which is a quadratic equation with coefficients 
, hence:
Then, applying the trigonometric equation, considering that 
due to the range of the cosine function:
It will take 2.28 minutes until the two trains are first equidistant from the child.

You're welcome and don't mention it, beforehand.
There's so little to this problem, and it will do you so much
more good to work it out yourself, that I'm just going to
point you in the right direction and give you a little push:
The area of a triangle is half of the product of its base and height.
A = (1/2) (base) (height)
I know you know what the base and height are, because
you just told them to US.
Base = 7.5m = 750 cm
Height = 6 cm.
Write those numbers in the formula in place of the words:
<span> A = (1/2) (base) (height)</span>
A = (1/2) (750 cm) (6 cm) .
Do that multiplication, and you've got your area.
Don't forget to keep the units when you multiply,
so that the answer is in units of cm² .
The answer may be a big number, and you may want to
change it to meter² instead of cm², to make it a smaller
number.
If you do that, remember that
1 meter = 100 cm
1 meter² = (1 meter) · (1 meter)
= (100 cm) · (100 cm)
= 10,000 cm²
X + 6 = x in math would be a Linear equation. Now in a question ther would be something that said x = whatever number x equals and then you could solve this question.
Hope I helped
Brainliest if satisfied :D
