Answer:

The area of a sector GHJ is $36.3\ cm^{2}$

Step-by-step explanation:

step 1

we know that

The area of a circle is equal to

$A=\pi r^{2}$

we have

$r=8\ cm$

substitute

$A=\pi (8)^{2}$

$A=64\pi\ cm^{2}$

step 2

Remember that the area of a complete circle subtends a central angle of 360 degrees

by proportion find the area of a sector by a central angle of 65 degrees

$\frac{64\pi}{360}=\frac{x}{65}\\ \\x=64\pi (65)/360$

Use $\pi =3.14$

$x=64(3.14)(65)/360=36.3\ cm^{2}$

Help asap plssssssss

Answer:

127

Step-by-step explanation:

m<PQR and m<RQS are supplementary angles so their sum is 180

3x - 5 + x + 1 = 180 add like terms

4x - 4 = 180 subtract 4 from both sides

4x = 176 divide both sides by 4

x = 44

m<PQR is 3x - 5 replace x with 44

3*44 - 5 = 127

(x-2)(x+7)

Nookie1986 [14]

So you use x = 2.
x-2 = 0
x+7=9
so (0,9) (x,y)
