Use the cosine formula
Cos(angle) = adjacent/ hypotenuse
cos(30) = x/8
Cos(30) can be written as sqrt(3)/2
Now you have :
sqrt(3)/2 = x/8
Multiply both sides by 8:
X = sqrt(3)/2 x 8
Simplify:
X = 4sqrt(3)
Answer:
There is no real solution.
Step-by-step explanation:
There is no solution because 5 is not equal to 7.
The expanded form of that number is 2,000,000 + 300,000 + 5,000 + 10 + 2.
Answer:
See below
Step-by-step explanation:
Circle equation standard form
(x-h)^2 + ( y-k)^2 = r^2 h, k is the center
All are centered at 0,0
radii are sqrt(225) = 15 sqrt 49 = 7 and sqrt 178
5.1234 to the nearest thousandths is 5.123
