Answer:
The angle with measure 60° is one of those angles that has a well-known cosine value: cos(60°) its C= 1/2.
Step-by-step explanation:
Yes because division always makes numbers smaller. For example: 12 divided by 4 equals 3.
Answer:
BC
Step-by-step explanation:
if u think about it, its pretty easy, if I'm wrong probably mistake but i tried my best
Firstly, we need to understand the formula of point-slope form:
Where x and y is the coordinates and m is the slope respectively.
To find the slope:
In this case:
We can then put the above slope and the point (-1,4) into the formula:
4-y = -1/2(-1-x)
-y = 1/2+1/2x-4
y = -1/2x+7/2
Alternatively:
y-4=-1/2(x-(-1))
y=-1/2x-1/2+4
y = -1/2x+7/2
Therefore the answer is y = -1/2x+7/2.
Hope it helps!
Answer:
x = 1
Step-by-step explanation:
a^2 + b^2 = c^2
The hypotenuse (c) and a side length is already given, so:
x^2 + 12 = 13
x^2 = 1
Square root of 1 = 1
So, x = 1
You can check it by 1+12=13
