Answer: 8:9
Step-by-step explanation:
Answer:
Step-by-step explanation:
The given equation is :
We need to decompose this equation.
We have,
So, is the decomposed form of the given expression.
Area=(Theta/2) * r^2 This should be it, obviously Theta is your angle and you should use radiants in theory.
Answer:
-1 and 1 are the zeros
Step-by-step explanation:
Graph it and youll see that the curve touches the x axis at (-1,0) and (1,0)
Since they're vertical angles, they're equal in degree measure
since they're equal, we can make the two expressions equal to each other
5a - 1 = 2a + 20
add 1 to both sides
5a = 2a + 21
subtract 2a from both sides
3a = 21
divide both sides by 3a
a = 7
now, plug the answer you found for a into one of the two expressions
5a - 1 becomes (5*7) - 1, which equals 34
to double check that they're equivalent (since they're vertical angles)
2a + 20 becomes (2*7) + 20, which equals 34
both angles are 34 degrees!
