Let the number be x
X *8 = 8x
8x-66= twice of the number
8x-66=2x
-66=2x-8x
-66=-6x
Divide both sides by -6
X=11
Answer: The abbreviation that supports the conclusion is SAS
Step-by-step explanation:
Given WS=NT
AS=OT
S=T
We have two triangles named WAS and NOT
where we have two sides (WS=NT and AS=OT)
and an angle(S=T) equal
Since the angle is between the two sides
So the postulate that supports is SAS
i.e Side Angle Side
Answer:
27.0 feet
Step-by-step explanation:
Length of an arc (s) = 2πrθ/360................. Equation 1
Where r = radius of the circle, θ = angle in degree substends by the arc at the center of the circle.
From the question,
Given: r = 9 feet, θ = 3 radian = 3 (57.2950) = 171.89°
Constant: π = 3.14
Substitute these values into equation 1
s = 2(3.14)(9)(171.89)/360
s = 9715.2228/360
s = 26.99 feet
s ≈ 27.0 feet
