First, find angle ECD using tan^-1(6/4), we get angle as 56.31
Now by proportionate, angle ECD and angle EBA are equal.
Hence you can use tan to find AB i.e, AB = 18/tan(56.31)= 12
Therefore, AB = 12
Answer:
$9.93
Step-by-step explanation:
Lacey would earn $9.93 in interest
Area of rectangle = length x width
6 x 3 = 18
area of triangle = base x height over 2
2 x 6 = 12
12 / 2 = 6
triangle 2
3 x 3 = 9
9 / 2 = 4.5
add everything together
4.5 + 6 + 18 = 28.5 m^2
Answer:
k = -1
Step-by-step explanation:
-3k + 6 = 10 + k
combine similar terms:
-3k - k = 10 - 6
simplify:
-4k = 4
simplify:
k = 4 / -4
k = -1
