If tan⁡ x= root of 3, and 180°

BartSMP [9]

Answer:

$\dfrac{1}{2}$

Step-by-step explanation:

If $180^{\circ}$ then angle $x$ is in the III quadrant.

Since $\tan x=\sqrt{3},$ then $x=240^{\circ}\ [180^{\circ}+60^{\circ}]$ (we get angle in the III quadrant)

Consider $\sin (x-210^{\circ}).$

If $x=240^{\circ},$ then

$\sin (240^{\circ}-210^{\circ})\\ \\=\sin 30^{\circ}\\ \\=\dfrac{1}{2}$

Answer:

$50.27cm^3$

Step-by-step explanation:

Given the dimensions of the cylinder as d=4cm and h=4cm, its volume can be calculated using the formula:

$V=\pi r^2 h\\\\=\pi \times (4/2)^2\times 4\\\\=16\pi cm^3=50.27cm^3$

Hence the volume of the cylinder is 50.27 $cm^3$

Kristine bought a vase that cost $5.99 and roses that cost $1.25 each.the total cost was $20.99.write and solve the equation to

Karolina [17]

20.99=5.99+1.25r (r =roses)
-5.99 -5.99
<u>15</u>=<u>1.25r </u> divide by 1.25 since they multiply to get the r alone
1.25 1.25
12=r so she bought 12 roses
(to check if its right just plug in your answer 12 where your r is and you should get 15
