I got 6 for my answer, but I'm not 100% sure if I'm right.
6(2x-11)+15=21
12x-66+15=21
12x-51=21
+51 +51
12x=72

Well flat means open so 180°
180° - 50° = 130° is the answer
Answer:
x = 5/2
Step-by-step explanation:
log4(x^2+5x)-log8(x^3)=1/log3(4)
log(x^2 + 5 x) / log(4) - log(x^3) / log(8) = log(3) / log(4)
log(x (x+5))/log(4) - log(x^3) / log(8) = log(3) / log(4)
(3 log(x (x+5)) - 2 log(x^3)) / log(64) = log(3) / log(4)
3 log(x (x+5)) - 2 log(x^3) = 3 log(3)
log((3 x)/(x+5))=0
x=5/2
