To get the answer the first thing you wanna do is plug in the numbers so that would be (8)(3)(12)/(2)(12)(4)= than you would multiply the numbers and you should get 288 divided by 96 and the answer is 3
Step-by-step explanation:
If triangles ADB and EDC are similar, then corresponding sides are proportional, from which we conclude:
BC/CD = AE/ED
BC / 21 = 6 / 18
Multiply by 21 on both sides,
BC = 6*21 / 18 = 21 / 3 = 7 units.
(note: Length BC is the same as length CB).
A^2+b^2=c^2 so c^2=12^2+16^2 which then simplifies to c^2=144+256 then simplify that to c^2=400. After that take the square root of c^2 and the square root of 400. So your answer is c=20
Ummm....did you mean like what is the answer to 6x100?
