A rectangular parking lot is 120 feet long and 75 feet wide. Diego made another scale drawing of the parking lot at a scale of 1
andrew11 [14]

Answer:

We kindly invite you to read carefully the explanation detailed below for further details.

Step-by-step explanation:

At first we understand that Diego converted length and wide units from feet to inches (1\,ft = 12\,in) and then he divided each term by 180, since he was using a reduction scale, so that rectangular parking lot can be represented on paper. That is:

Step 1 - Unit conversion:

l = 120\,ft (l - Length)

l = 120\,ft\times \frac{12\,in}{1\,ft}

l = 1440\,in

w = 75\,ft (w - Width)

w = 75\,ft\times \frac{12\,in}{1\,ft}

w = 900\,in

Step 2 - Applying scaling:

l' = \frac{l}{180} (l' - Scaled length)

l' = \frac{1440\,in}{180}

l' = 8\,in

w' = \frac{w}{180} (w' - Scaled width)

w' = \frac{900\,in}{180}

w' = 5\,in

If BC = 6.5, CD = 7.8, and AD = 12.2, find AB to the nearest tenth.
Sladkaya [172]
This can be solved using the angle bisector theorem. Note that line segment AD is the angle bisector of triangle DAB from angle DAB. Therefore, we know that the ratios \frac{\text{AD}}{\text{CD}} and \frac{\text{AB}}{\text{CB}} are equal. Solving, we get \frac{\text{12.2}}{\text{7.8}}=\frac{\text{AB}}{\text{6.5}}. Cross multiplying, we get 79.3 = 7.8x, and solving this equation we get x = 10.1666... \approx 10.2. 10.2 is your answer.
