Simplify this fraction -17/34
1 answer:
In order to simplify this fraction we need to find greatest common factor of 17 and 34.
Let us first find all possible factors of 17 and 34.
factors of 17 are 1 and 17 (since 17 is a prime number)
factors of 34 are 1, 2, 17 and 34.
common factor of 17 and 34 is 17
so we divide both numerator and denominator by 17.
dividing -17 by 17, we have -1
dividing 34 by 17 we have 2
So our answer is -1/2

Answer:
1.) ≈ 3.652
2.) I would say something about how the A in front of cos in the equation would change to 90, rather than stay 75 (in the equation for the step by step), but it would be easier to just use the Pythagorean theorem.
Step-by-step explanation:
I think we may have the same class so hopefully this helps:
1.) --> law of cosines formula.
--> plugged in numbers; when you draw the triangle, the included angle would be A, and the opposite side would be a. B and b, and C and c are opposite each other. In this case, a is the hypotenuse.
--> in between steps.
--> more simplifying.
--> answer
2.) This one is just an explanation: The 75 in the equation is the given angle, which is a. If this changes, it would just change in the equation too. And obviously, if it's 90 degrees, you can just use Pythagorean theorem a^2+b^2=c^2.
Good luck! :)
