For the △ACD is shown below, select all the true statements. Lengths are rounded to the nearest tenth.

1. ∠ADB = 30°
2. △ABD ∼ △ACD
3. CD = 33.7 centimeters
4. BD = 37.2 centimeters

Option B is correct .i.e., 30 square centimeters

Step-by-step explanation:

We have to find area of ACDE.

From given figure ACDE is made up of two triangles ΔBCD &  ΔABE

So, Area of ACDE = Area of ΔBCD + Area of ΔABE

Area of traingle =

⇒ Area of ACDE =  

Therefore, Option B is correct .i.e., 30 square centimeters

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.
