Solve for a:

$5a+c=-8a\ \ \ |-c\\\\5a=-8a-c\ \ \ |+8a\\\\13a=-c\ \ \ |:13\\\\\boxed{a=-\dfrac{c}{13}}$

Solve for c:

$5a+c=-8a\ \ \ \ |-5a\\\\\boxed{c=-13a}$

Answer:

x = 15.3°

Step-by-step explanation:

Trig identities:

$sin(x)=\dfrac{O}{H} \ \ \ \ \ cos(x)=\dfrac{A}{H} \ \ \ \ \ tan(x)=\dfrac{O}{A}$

where

$sin(46)=\dfrac{11}{x}\\\\\implies x=\dfrac{11}{sin(46)}\\\\\implies x=15.3$

Volume = πd^2h/4
245 = π x d^2 x 5/4
d^2 = (245 x 4)/5π = 62.39
d = sqrt(62.39) = 7.9 units
