Hello.
First, let the number be r.
5 times r is written like this:
Now, add 45:
Now, the sum of 5r+45 is equal to the sum of 85 and 140:
In order to solve this equation, we need to add 85 and 140:
Now, subtract 45 from both sides:
The last step is to divide both sides by 5:
Therefore, the answer is
I hope it helps.
Have a nice day.
So.. checking the picture below
we can say y = y, or just do a substitution and end up with
once you know, how long is "x", then you can simply use the cosine of 72° to get "r"
thus
