Answer:

The length of Vindale Avenue = x = AB = 6 m

Step-by-step explanation:

Given data

Diagonal distance AC = 10 m

BC = length of castroville Street = 8 m

Let the length of Vindale Avenue = x

Thus a Δ ABC is formed.

From the Δ ABC

$AC^{2} = AB^{2} + BC^{2}$

$10^{2} = x^{2} + 8^{2}$

$x^{2} = 100 - 64$

$x^{2} = 36$

x = 6 m

Therefore the length of Vindale Avenue = x = AB = 6 m

Answer:

clockwise
90°
origin

Step-by-step explanation:

The answer statement tells you the transformation is a rotation. The original is in the 2nd quadrant, and the image is in the 1st quadrant, representing a clockwise rotation. AB points east, while A'B' points south, a rotation of 90° (clockwise). Each image point is the same distance from the origin as its preimage point. The origin is the center of rotation.

∆ABC is transformed by a <u> clockwise </u> rotation <u> 90 </u> degrees with a center at the <u> origin </u>.

Solve the equation for x. 1 3 (6x − 9) = −33

KIM [24]

Answer:

<u>x = 1.07</u>

Step-by-step explanation:

13 ( 6x - 9) = -33

78x - 117 = -33 ( opening brackets and multiplying )

78x = 84 ( - 117 taken to the other side makes it positive)

x = 84 / 78

x = <u>1.07</u>
