Ax+by=c but A can't be lower than one and can't be a negative
1+2+3+... +n=
((1+n) x n) /2
is that the things you want
Answer:
46.07
Step-by-step explanation:
CAH (cosine=adjacent/hypotenuse)
cos (71)=15 (adjacent)/x (hypotenuse)
x=15/cos(71)
x=46.07
It is a scalene triangle as all the sides are unequal in length.
For this case we can pose the problem as a rectangle triangle.
We know the hypotenuse and one side of the triangle.
Therefore, the other side is given by:
10 ^ 2 = 6 ^ 2 + x ^ 2
Clearing x we have:
x ^ 2 = 10 ^ 2-6 ^ 2
x = root (10 ^ 2-6 ^ 2)
x = 8 feet
Answer:
The length in feet of the garden is:
x = 8 feet
