First lets subract 1.2 from each side to get
2.3x+2.5x=8-4.3x
Then Combine like terms to get
4.8x+8-4.3x
Then add 4.3 to each side
9.1x=8
x equals about 0.88

2.3x + 1.2 + 2.5x = 9.2 - 4.3
4.8x + 1.2 = 9.2 - 4.3x
4.8x = 8 - 4.3x
9.1x = 8
x = 0.87

What is 180(n-2)=s when solving for N

Sergio039 [100]

Answer:

n = s/180 +2

Step-by-step explanation:

180(n-2)=s

Distribute

180n - 360 =s

Add 360 to each side

180n -360+360 = s+360

180n = s+360

Divide each side by 180

180n/180 = s/180 + 360/180

n = s/180 +2

A sector with an area of 26pie cm^2 has a radius of 6 cm. What is the central angle measure of the sector in radians?

Zolol [24]

Answer:

The central angle measure of the sector in radians is $\theta=\frac{13}{9}$ .

Step-by-step explanation:

A sector of a circle is the portion of a circle enclosed by two radii and an arc. It resembles a "pizza" slice.

The area of a sector when the central angle is in radians is given by

$A=(\frac{\theta}{2})\cdot r^2$

where

r = radius

θ = central angle in radians

We know that the area of the sector is $26 \:cm^2$ and the radius is 6 cm. Applying the above formula and solving for the central angle ( $\theta$ ) we get that

$26=(\frac{\theta}{2})\cdot (6)^2\\\\\left(\frac{\theta}{2}\right)\left(6\right)^2=26\\\\\frac{\frac{\theta}{2}\cdot \:6^2}{36}=\frac{26}{36}\\\\\frac{\theta}{2}=\frac{13}{18}\\\\\theta=\frac{13}{9}$
