Answer:

$x = \frac{21}{4} \\$

Step-by-step explanation:

$\frac{2x+3}{15} = \frac{9}{10} \\ \\ (10)(2x + 3) = (9)(15) \\ 20x + 30 = 135 \\ 20x = 135 - 30 \\ 20x = 105 \\ x = \frac{105}{20} \\ \\ x = \frac{21}{4}$

A sector with a radius of 15 cm has a central angle measure of 8pie/5

Citrus2011 [14]

Answer:

The area of the sector is $180\pi \ cm^2$ .

Step-by-step explanation:

We have,

Radius of circle is 15 cm

Central angle is $\dfrac{8\pi}{5}\ \text{radian}$

It is required to find the area of the sector. The formula used to find the area of sector is given by :

$A=\dfrac{1}{2}r^2\theta$

Plugging all the values in above formula as :

$A=\dfrac{1}{2}\times 15^2\times \dfrac{8\pi}{5}\\A=180\pi \ cm^2$

So, the area of the sector is $180\pi \ cm^2$ .
