What is the complement of a 47 degree angle?

complementary angles add to 90 degrees

x+47 = 90

subtract 47 from each side

x = 90-47

x = 43

43° is your answer

Step-by-step explanation:

Note that "complement" means 90° (while "supplement" means 180°)

Subtract 47 from the total, 90

90 - 47 = 43

43° is your answer

y=3x+4

step-by-step explanation:

given the points a(0,4) and b(-4, -8)

eqn of line ab: (y-4)/(x-0)=(-8-4)/(-4-0)

(y-4)/x=-12/-4=3

y=3x+4
