What equation Is correct ?
1 answer:
Hi there!
Let's first have a look at the basic goniometric statements, which say the following:
When we're looking from the point of view of angle G, we have the following data:
- The length of the opposite side is 15
- The length of the adjecent side is 8
- The length of the hypotenuse is 17
Now plug in this data into our general formulae.
Hence, answer B. is correct.
~ Hope this helps you!

Answer:
(1)
And for this case we know the following condition "The length of the field is 7 yards less than quadruple the width" and we can write this :
And replacing into equation (1) we got:
Adding 14 in both sides we got:
And dividing 10 on both sides we got:
And then we can solve for X and we got:
Step-by-step explanation:
For this case we can set up the following notation:
X represent the lenght
Y represent the width
And since we have a rectangular playing filed the perimeter is given by:
(1)
