Answer:
CD=14 cm and DE=21 cm
Step-by-step explanation:
Let the rhombus's side be x cm, DN=NF=FM=DM=x xm.
Triangles CDE and FNE are similar, thus,
or
Hence,
and
Since the perimeter of the triangle CDE is 55 cm, we have that
Therefore, CD=14 cm and DE=21 cm

Step-by-step explanation:
Angle C must = [180 - 73 - 57 ] = [180 - 130] = 50°
And using rhw Law if Sines, we have.....
AB/sin C = AC/sin B → 24/sin(50) = AC/sin(73) → AC = 24*sin(73)/sin(50) = about 29.96 in
Step-by-step explanation:
curved surface area =
perimeter of triangular base × length
= 3×8 + 12
= 24 + 12
= 36mm^2
total surface area
= curved surface area + 2× area of triangular base
= 36 + 2 × root3 ×8^2 ÷ 4
= 36 + 2 × root3 × 16
= 36 + 2× 27.71
= 36 + 55. 425
= 91.425 mm^2
