Answer:
To find a b and c in a quadratic equation, the x^2 number is a, so 7x^2 is your a value, your b value is just the x, so your b value is -9, and your c value is the regular number, which is 18. a=7x^2 b=-9x c = 18. So your answer is answer B.
Step-by-step explanation:
Y-y1=m(x-x1)
y+18=1(x+8)
y=x-10
parallel lines have the same slope

Hi there!
Let th' required angle = X
Then,
• Complement of th' angle = 90 - X
• Supplement of th' angle is = 180 - X
According to th' question,
Sum of Complement and Supplement :-
(90 - X) + (180 - X) = 200
⇒ 90 - X + 180 - X = 200
⇒ 270 - 2X = 200
⇒ 2X = 270 - 200
⇒ 2X = 70
⇒ X =

= 35
Hence,
Th' measure of the angle is 35°
