The decimal value for 12/9 is 1.34
You can use the quadratic formula with it which will be easier
or simple factoring
it will be (5x-11)(7x+4)
Answer:
C
Step-by-step explanation:
I think you mean what is equal to 27:81. I will give you 3 ratios. (Same meaning as fractions). 27:81=1:3, 3:9, and 54:12
In this situation I would use cosine to find m∠G.
Cosine = Adjacent side ÷ Hypotenuse
RG being the adjacent side and TG being the hypotenuse, you would set up the equation like this
cos(g) = 8/17
then solve
cos(g) = 0.47058
simplify
g = cos^-1(0.47058)
and you get
m∠G = 61.9°
So your answer would be 62°
