Answer:
x = 65/16, y = 37/16
Step-by-step explanation:
solve the system algebraically
x+3y=11
4x-4y=7
Try substitution.
let x = 11 - 3y
Plug in.
4(11 - 3y) - 4y = 7
44 - 12y - 4y = 7
44 - 16y = 7
37 = 16y
y = 37/16
x = 11 - 3*y
x = 11 - 3*(37/16)
x = 11 - 111/16
x = 65/16
The area of the sector with a radius of 20 units and a central angle of 162° is 180π unit².
<h3>What is the sector of a circle?</h3>
A sector is the portion of a circle enclosed by two radii and an arc, where the smaller area is known as the minor sector and the larger is the major sector.
The radius of the sector =20 units
Central angle subtended by sector = 162° = 162π/180 radians
As we know the area of a sector= 0.5r²α
where r is the radius and α is the central angle.
So, the area of the given sector = 0.5*20²* 162π/180
The area of the given sector = 180π unit²
Therefore, The area of the sector with a radius of 20 units and a central angle of 162° is 180π unit².
