57
Step-by-step explanation:
To calculate the sine of an angle, simply divide the length of the opposite side, 479.16, by the length of the hypotenuse, 610. To get the cosine, divide the length of the adjacent side, 377.5, by the length of the hypotenuse, 610.
Answer:
Khan Academy is a great website for Algebra l math
If you have the time and money Kumon is a good in-person learning assistance (I-H level is about algebra I)
Step-by-step explanation:
We can use completing the square.We add 16 and subtract 7 to both sides. Now we get m^2+8m+16=9. The left sides becomes (m+4)^2=9. Taking the square root of both sides and subtracting 4 we get -1 and -7.
Answer:

Step-by-step explanation:
We start by adding
to both sides, giving
, which after simplifying gives
.
We then add
to both sides, giving
, which after simplifying gives
.
We can then divide both sides by
, giving
, which after simplifying gives
, or
. So, x is 5.
