The normal form of a line is given by the equation x * cos theta + y * sin theta = p where theta is the angle of the normal line from the positive x-axis and p is the length of the normal line. Converting to normal line form, the equation must first be converted into standard form: 2x + 7y = 4. Then dividing the whole equation by sqrt(a^2 + b^2): sqrt(2^2 + 7^2) = sqrt(53). Hence, the equation becomes 2 / sqrt(53) * x + 7 / sqrt(53) * y = 4 / sqrt(53). Therefore, the length of the normal line is 4 / sqrt(53), and the angle is arctan(7/2) = 74.05 degrees.

Answer:
I cannot answer this. There are no letters. I am sorry that I couldn't help you.
Step-by-step explanation:
5a+8
Answer is NOT 5a+8
5(a+3) Multiply the bracket by 5
5(a)+5(3)
5a+15
Correct answer is supposed to be: 5a+15
Answer:
I think complementary angles
