Since BE bisects ∠ ABD then ∠ DBE = ∠ ABE, thus
8x - 14 = 6x + 2 ( subtract 6x from both sides )
2x - 14 = 2 ( add 14 to both sides )
2x = 16 ( divide both sides by 2 )
x = 8
Thus ∠ ABE = 6x + 2 = 6(8) + 2 = 48 + 2 = 50°
(16)
Since BE bisects ∠ ABD then ∠ ABE = ∠ DBE = 12n - 8 and
∠ ABD = ∠ ABE + ∠ DBE, that is
22n - 11 = 12n - 8 + 12n - 8 = 24n - 16 ( subtract 24n from both sides )
- 2n - 11 = - 16 ( add 11 to both sides )
- 2n = - 5 ( divide both sides by - 2 )
n = 2.5
Thus
∠ EBD = 12n - 8 = 12(2.5) - 8 = 30 - 8 = 22°

Answer:
a, d, b, c
Step-by-step explanation:
Given that:
Perimeter=194 cm
Width=w
Length, L= 4w-3
Formula for perimeter of rectangle:
P=2(L+W)
Put values
194=2(4w-3+w)
194=2(5w-3)
Divide both sides by 2.
97=5w-3
Add 3 to both sides
100=5w
w=20
So length= 4 (20) -3 = 80-3 =77 cm
and width= 20 cm
Answer: Length=77 cm and width=20 cm
Answer:
To find the area of a triangle, multiply the base by the height, and then divide by 2. The division by 2 comes from the fact that a parallelogram can be divided into 2 triangles. For example, in the diagram to the left, the area of the parallelogram.
