Step-by-step explanation:

You have to have tracing paper or patty paper (cause that's what my teacher uses). Next you draw the figure along with the x and y-axis on it as well. Then you mark the x and y-axis and rotate the paper 90 degrees clockwise. Lastly if the x-axis is on the y-axis, mark it as the y-axis and if the y-axis is on the x-axis, also mark it as the x-axis.

I hope this helped :)

Answer: $\bold{b)\quad \dfrac{5}{6},\ \dfrac{25}{6}}$

<u>Step-by-step explanation:</u>

$12cos\bigg(\dfrac{2\pi}{5}x\bigg)+10=16\\\\\\12cos\bigg(\dfrac{2\pi}{5}x\bigg)=6\\\\\\cos\bigg(\dfrac{2\pi}{5}x\bigg)=\dfrac{1}{2}\\\\\\cos^{-1}\bigg[cos\bigg(\dfrac{2\pi}{5}x\bigg)\bigg]=cos^{-1}\bigg(\dfrac{1}{2}\bigg)$

$\text{Use the Unit Circle to determine when}\ cos=\dfrac{1}{2}\quad \rightarrow \quad\text{at}\ \dfrac{\pi}{3}\ and \ \dfrac{5\pi}{3}\\\\\\\dfrac{2\pi}{5}x=\dfrac{\pi}{3}\qquad and\qquad \dfrac{2\pi}{5}x=\dfrac{5\pi}{3}\\\\\\\bigg(\dfrac{5}{2\pi}\bigg)\dfrac{2\pi}{5}x=\dfrac{\pi}{3}\bigg(\dfrac{5}{2\pi}\bigg)\quad and\quad \bigg(\dfrac{5}{2\pi}\bigg)\dfrac{2\pi}{5}x=\dfrac{5\pi}{3}\bigg(\dfrac{5}{2\pi}\bigg)\\\\\\.\qquad \qquad \large\boxed{x=\dfrac{5}{6}\qquad and \qquad x=\dfrac{25}{6}}$

Answer:

Step-by-step explanation:

Find the volume of the sphere first :

V sphere = $\frac{4}{3}$ π 6^3 = 902.51

Then use the volume of the sphere to find the height :

Formula = V/π $r^{2}$

902.51/π(6)^2 = 8.004 (rounded is 8)

hope this helped :)

in triangle ABC the measure of angle B is 24° more than three times the measure of angle a the measure of angle C is 51° more th

ValentinkaMS [17]

M∠A = x
m∠B = 3x+24
m∠C = x + 51

x + 3x+24 + x + 51 = 180
5x + 75 = 180
5x = 180 - 75
5x = 105
x = 105/5
x = 21

m∠A = x = 21°
m∠B = 3x+24 = 3*21 + 24 = 87°
m∠C = x + 51 = 21 + 51 = 72°
