How long is the arc of a circle subtended by a central angle of 1 radian if the radius of the circle is 17 units?

Use the formula S = xr.

Note: I am using x in place of theta since there is no theta symbol on my keyboard.

We want to find S, the arc of the given circle.

S = (1 rad)(17 units/rad)

Notice that both rad cancel out.

Note: rad is radians for short.

S = 17 units

x = 10.1

step-by-step explanation:

all of the angles of a tirangle add up to 180º

180 - 65 = 115 (since we already know the value of one angle)

(2x + 7) + (8x + 7) = 115

(combins like terms) 10x + 14 = 115

(isolate the variable subtract 14 from both sides): 10x = 101

(find the variable divide both sides by 10): x = 101/10

x = 10.1

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4
