The drawing seems to suggest that angles BFA, AFE and EFD span a straight angle, just like angles BFC and CFD

This means that you have

$BFA+AFE+EFD=180$

But we know that both BFA and EFD measure 70 degrees, so the equation becomes

$[tex]70+AFE+70=180 \iff AFE + 140 = 180$

So, if you subtract 140 from both sides, you have

$AFE = 180-140 = 40$

Answer:

$a=22,\\b=31,\\c=13$

Step-by-step explanation:

When choosing equations to write, make sure you choose a pair that allow you to isolate a variable and solve for it.

Sample solution:

$a+25+28=16+25+34,\\\\a+28=16+34,\\a+28=50,\\a=\boxed{22}$

$16+b+28=16+25+34,\\b+44=75,\\b=\boxed{31}$

$34+c+28=16+25+34,\\c+28=41,\\c=\boxed{13}$

Blababa [14]

Answer:

$a)\: \frac{3}{2} \pi$

$b) \:\frac{47}{5} \pi$

Step-by-step explanation:

$y=3\sqrt x,\:\:y=3,\:\:x=0$

a) about the line y = 3

$3\sqrt x=3$ ⇒ $x = 1$ is the intersection point

So,

$V=\int\limits^1_0\pi(3-3\sqrt x)^2\:dx=\pi\int\limits^1_0(9-18\sqrt x+9x)\:dx=\\\\=\pi(9x-12x^{3/2}+9/2x^2)|^1_0=\pi(9-12+9/2)=\frac{3}{2} \pi$

b) about the line x = 5

$y=3\sqrt x$ ⇒ $x=y^2/9$

So,

$V = \int\limits^3_0\pi([5-0]^2-[5-y^2/9]^2)\:dy=\pi\int\limits^3_0(25-25+10y^2/9-y^4/81)\:dy=\\\\=\pi(10y^3/27-y^5/405)|^3_0=\pi(10-3/5)=\frac{47}{5} \pi$
