Answer:
36
Step-by-step explanation:
EF = is 1/3 of 15
Since the triangles are similar, then the perimeters are similar.
The perimeter of EDF is 12
The perimeter of ABC should be 3 times as large.
3*12 = 36
The perimeter of ABC = 36
So we start off by subtracting 137.3 from 180 getting 42.5. If you add the ratios up (3+4) you get 7 and 7 should equal 42.5. thus,
42.5/7= 85/14
(85/14)*3=18.2 or (255/14 to be exact)
(85/14)*4= 24.29 or (170/7 to be exact)
Answer:
(B) square
Step-by-step explanation:
Square (regular quadrilateral): all four sides are of equal length (equilateral), and all four angles are right angles.
