Answer:
ED = 8 units
Step-by-step explanation:
ΔAEB and ΔDEC are similar triangles, hence the ratios of corresponding sides are equal, that is
= , that is
= ( cross- multiply )
6(2x + 4) = 9(x + 4) ← distribute parenthesis on both sides
12x + 24 = 9x + 36 ( subtract 9x from both sides )
3x + 24 = 36 ( subtract 24 from both sides )
3x = 12 ( divide both sides by 3 )
x = 4
Hence ED = x + 4 = 4 + 4 = 8 units

Answer:
12 square feet
Step-by-step explanation:
A=Area
b=Base
h=Height
To find the area of an triangle, you use the formula A=1/2bh
you plug in the the area and the height to get:
48=1/2xbx8
you do the maths and you get
b=12
