A piece of land is in the shape of a sector. Its area is 900 sq ft, while its arc length is 30 ft. What is the measure of the angle between the two radii of the sector?

C= 2 radians.

Step-by-step explanation

Length of arc = r C where r = the radius and C is the angle in radians.

Area of the sector = 1/2 r^2 C

So we have:

30 = rC  and

900 = 1/2 r^2 C

From the first equation we have  r = 30/C so substituting for r:

900 = 1/2 (30/C)^2 * C

900 = 0.50 (900/C^2) * C

900 =  450/C

C= 2 radians.

step-by-step explanation:

5×5×5+2(8)÷2(2)+3(3)

15+16÷4+9

31÷13

do 31÷13 and u will get ur answer

step-by-step explanation:

we are given

since, we have to isolate x on anyone side

so, we can move all x terms on one side

subtract both sides by 2x

add both sides by 9

divide both sides by 4

we get
