ΔABE ~ ΔDCE
AB=AE*DC/DE=18*4/6=12

As AD is common tangent,

<BAE=90=<CDE

Also <BEA=<CED as they are opposite angles

By AAA, the two triangles, ABE and DCE, are similar

so AB/EA = DC/ED

AB = EA * DC/ED = 18 * 4/6

= 12

1: What is Abby's total spent on transportation?
stealth61 [152]

Answer:

1. Total spent on transportation $222.2.

2. $ 192.5

3. She spends $30 over the guideline.

Step-by-step explanation:

As per the image attached:

Total monthly spent on transportation = Total monthly car payment + Spent on gas fuel

Total monthly spent on transportation = 120 + 37.9 + 28.4 + 35.9 = $222.2

So, Answer 1. Abby's total spent on transportation = $222.2

Calculating the percentage:

\Rightarrow \dfrac{\text{Spent on transportation}}{\text{Total monthly income}}

\Rightarrow \dfrac{222.2}{1750}\times 100 =12.69\%

Calculating 11% as per the guideline:

1750 \times \dfrac{11}{100}\\\Rightarrow \$192.5

Answer 2. As per the guideline, she should spend $192.5 on transportation.

Difference between spending and guideline = $222.2 - $192.5 = $29.7

Answer 3. She spends $29.7 over the guideline.
