Answer:

\huge{ \boxed{ \bold{ \sf{ \pink{80°}}}}}

Step-by-step explanation:

✰ \underline{ \sf{First, \: Let's \: learn \: about \: internal \: angles \: of \: a \: triangle}}

The angles which are formed inside by the joining of arms of a triangle is called interior angles of a triangle. According to the figure provided , In ∆ ABC , ∠ABC , ∠ ACB , ∠ BAC are interior angles because they lie inside the ∆ ABC and sum of such interior angles is always 180°.

❀ \sf{Now, \: Let's \: solve} :

☄ \underline{ \underline{ \sf{Provided : }}}

  • ∠B = 3x°
  • ∠ C = 4x°
  • ∠ A = 2x°

☄ \underline{ \sf{To \: Find :}}

  • Measure of C

✏ \text{Set \: up \: an \: equation \: and \: solve \: for \: x.}

\text{{∠a \:  +  \: ∠ \: b \:  +  \: ∠ \: c \:  =  \: 180 \degree}}

→ \sf{2x + 3x + 4x = 180 \degree}

→ \sf{9x = 180  \degree}

→ \sf{ \frac{9x}{9}  =  \frac{180  \degree }{9} }

→ \sf{x =  20 \degree}

The value of x is 20°. As we are asked to find the measure of ∠C , substituting the value of x in 4x :

\text{∠c = 4x}

→ \sf{∠ \: c \:  = 4 \times 20 \degree}

→ \boxed{ \bold{ \pink{   \sf{∠c \:  = 80 \degree}}}}

Hence , The measure of ∠ C is 80 °

Hope I helped ! ッ

Have a wonderful day / night ! ♡

Find the surface area of the solid generated by revolving the region bounded by the graphs of y = x2, y = 0, x = 0, and x = 2 ab
Nikitich [7]

Answer:

See explanation

Step-by-step explanation:

The surface area of the solid generated by revolving the region bounded by the graphs can be calculated using formula

SA=2\pi \int\limits^a_b f(x)\sqrt{1+f'^2(x)} \, dx

If f(x)=x^2, then

f'(x)=2x

and

b=0\\ \\a=2

Therefore,

SA=2\pi \int\limits^2_0 x^2\sqrt{1+(2x)^2} \, dx=2\pi \int\limits^2_0 x^2\sqrt{1+4x^2} \, dx

Apply substitution

x=\dfrac{1}{2}\tan u\\ \\dx=\dfrac{1}{2}\cdot \dfrac{1}{\cos ^2 u}du

Then

SA=2\pi \int\limits^2_0 x^2\sqrt{1+4x^2} \, dx=2\pi \int\limits^{\arctan(4)}_0 \dfrac{1}{4}\tan^2u\sqrt{1+\tan^2u} \, \dfrac{1}{2}\dfrac{1}{\cos^2u}du=\\ \\=\dfrac{\pi}{4}\int\limits^{\arctan(4)}_0 \tan^2u\sec^3udu=\dfrac{\pi}{4}\int\limits^{\arctan(4)}_0(\sec^3u+\sec^5u)du

Now

\int\limits^{\arctan(4)}_0 \sec^3udu=2\sqrt{17}+\dfrac{1}{2}\ln (4+\sqrt{17})\\ \\ \int\limits^{\arctan(4)}_0 \sec^5udu=\dfrac{1}{8}(-(2\sqrt{17}+\dfrac{1}{2}\ln(4+\sqrt{17})))+17\sqrt{17}+\dfrac{3}{4}(2\sqrt{17}+\dfrac{1}{2}\ln (4+\sqrt{17}))

Hence,

SA=\pi \dfrac{-\ln(4+\sqrt{17})+132\sqrt{17}}{32}
