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! :)
Since the x coordinates are 2 for (2,-2) and (2,5), you can assume that the 4th vertex's x coordinate would be (-1) since there is only one coordinate with -1 given.
It should be (-1,-2) since the 1st vertex should correspond to the 4th
Answer:
The answer is "None of the above".
Step-by-step explanation:
In this question, both the team given data is the same, and when the coach calculates its value it will give the same value, that's why we can say that all the choices were wrong.
That expression can be written as:
Hope it helped,
Happy homework/ study/ exam!
