Answer:

21x = 14

x = 1.5

Step-by-step explanation:

(-4)3y - 9x = -6

(3)4y - 12x = -8

-12y-9x=-6

12y-12x=-8

0 -21x = -14

-21x/- = -14/-

21x = 14

How to find value of y in polygon JKLM

Yuki888 [10]

Answer:

y = 22.5

Step-by-step explanation:

Here, the 4 angles shown are all exterior angles of the polygon.

The sum of the exterior angles of a polygon is ALWAYS 360°

<em>So we add up the 4 angles (given in terms of y) and sum it to 360 and solve for y:</em>

$4y+2y+6y+4y=360\\16y=360\\y=\frac{360}{16}=22.5$

y = 22.5

A sector with a radius of 8 cm has an area of 56pi cm2. What is the central angle measure of the sector in radians?

Maurinko [17]

Answer:

$\frac{7\pi}{4}$ .

Step-by-step explanation:

Given information:

Radius of circle = 8 cm

Area of sector = $56\pi\text{ cm}^2$

Formula for area of sector is

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

where, r is radius and $\theta$ is central angle in radian.

Substitute $A=56\pi$ and r=8 in the above formula.

$56\pi=\dfrac{1}{2}\theta (8)^2$

$56\pi=\dfrac{64}{2}\theta$

$56\pi=32\theta$

$\dfrac{56\pi}{32}=\theta$

$\dfrac{7\pi}{4}=\theta$

Therefore, the measure of the sector in radians is $\frac{7\pi}{4}$ .
