Find the Least Common Multiple<span> of the </span>denominators<span> (which is called the Least </span>Common Denominator<span>). Change each fraction (using equivalent fractions) to make their </span>denominators<span> the </span>same<span> as the least </span>common denominator<span>. Then add (or subtract) the fractions, as we wish!</span>
There are 2 basic trangles used in SAT,
45-45-90
30-60-90
if you look in the attachment you will know the relationship between each so
with a 30-60-90 triangle which you have
hypotonuse=2x
hypotonuse=12
2x=12
divide by 2
x=6
I'm not sure about the length, but I'm assuming you mean the longer side
the measure of each leg is 6 and 6 times√3
the lonnger one is 6√3
the answer is 6√3 meters
answer:
21 + 3x (you would not put the x again since it is already given)
step-by-step explanation:
- we have to distribute 3 to the expression in the parenthesis
3 (7 + x)
= 21 + 3x
- this will be the expression once we distribute
Answer:
A. 9.8ft
Step-by-step explanation:
work out arc length using this formula
![2\pi \: \times r \times \frac{\theta}{360}](https://tex.z-dn.net/?f=2%5Cpi%20%5C%3A%20%20%5Ctimes%20r%20%20%20%20%5Ctimes%20%5Cfrac%7B%5Ctheta%7D%7B360%7D%20)
r is the radius, 7 in this case and theta(the symbol above 360) is the angle, 80 in this case
