83-63=20
So your answer is 20
Answer:

Step-by-step explanation:
In a quadratic equation in the Standard form

You need to remember that "a", "b" and "c" are the numerical coefficients (Where "a" is the leading coefficient and it cannot be zero:
).
You can observe that the given quadratic equation is written in the Standard form mentioned before. This is:

Therefore, you can identify that the values of "a", "b" and "c" are the following:

Step-by-step explanation:
letter b ang sagot sa number 6
Answer:
67.97
Step-by-step explanation:
let AC be length of ladder and BC be distance between ladder and wall and angle be theta
Now,
costheta=BC/AC
THETA =COS^-1(3÷8)
THETA=COS^-1(0.375)
THETA=67.97 DEGREE
