Answer:

hence <A =41°

Step-by-step explanation:

$x + 6 + 2x + 5 + 2x - 6 = 180 \\ (sum \: of \: inside \: the \: triangle \: is \: 180) \\ 5x + 5 = 180 \\ 5x = 180 - 5 \\ x = \frac{175}{5 } \\ x = 35 \\ now \: putting \: the \: value \: of \: x \: in \: ange \: a \\ < a = x + 6 \\ < a = 35 + 6 \\ < a = 41$

Volume of cylinder = πr²h = π x 4² x 6 = 96π

volume of cone = 1/3πR²H = 1/3π x 8² x 12 = 256π

You can see that volume of cone is more than twice of volume of cylinder. So she is not correct

How do i graph 3tan(x+30)

Marina CMI [18]

$y = 3tan(x + 30)$
$y = 3(\frac{tan(x) + tan(30)}{1 - tan(x)tan(30)})$
$y = \frac{3(tan(x) + tan(30))}{1 - tan(x)tan(30)}$
$y = \frac{3(tan(x)) + 3(tan(30))}{1 - tan(x)tan(30)}$
$y = \frac{3tan(x) + 3tan(30)}{1 - tan(x)tan(30)}$
