Answer:
I'm pretty sure it is A
Step-by-step explanation:
Answer:
EC, DE, CD
Step-by-step explanation:
∠D=34° ∠C=47° ∠E= 180-34-47=99°
∠D < ∠C < ∠E
By the theorem: If one angle in a triangle is larger than another angle in a triangle, then the side opposite the larger angle will be longer than the side opposite the smaller angle.
EC < DE < CD
Middle square area= 8x8=64
one triangle area = (8x8)/2
multiply the triangel area by four and add the square area-- (4x32)+64=192
12/68= 43/d
Divide 43 by 12 which is 3.583
then multiply 68 by 3.583
So d is 243.6
