In the rectangle below, AE = 3x + 6, CE =6x-9, and mZEDA= 55°.<br> Find BE and m ZEAB.
tekilochka [14]

Answer:

BE = 21

m∠EAB = 45°

Step-by-step explanation:

The given dimensions in the rectangle are;

The length of AE = 3·x + 6

The length of CE = 6·x - 9

m∠EDA = 55°

From the properties of a rectangle, we have;

The diagonals of a rectangle bisect each other,

The lengths of the diagonals are equal

Therefore;

AC = BD

Diagonal BD bisects diagonal AC, therefore, AE = CE

Plugging in the values of AC and AE, we have;

3·x + 6 = 6·x - 9

∴ 6·x - 3·x = 6 + 9 = 15

3·x = 15

∴ x = 15/3 = 5

Therefore, we have;

AE = CE = 3·x + 6 = 3×5 + 6 = 21

AC = AE + CE = 21 + 21 = 42 = BD

BD = BE + DE and for rectangle ABCD, BE = DE

∴ BD = BE + BE = 2·BE = 42

∴ BE = 42/2 = 21

<em>BE = 21</em>

m∠EDA = m∠EAD = 55° by base angle of isosceles triangle ΔAED

m∠DAB = 90° = m∠EAD + m∠EAB

∴ m∠EAB = 90° - m∠EAD = 90° - 55° = 45°

<em>m∠EAB = 45°.</em>

Sandra rode her bike 54 miles in one day. She rode 6 times the
stira [4]

Answer:

54 = 6b

Step-by-step explanation:

Sandra rode her bike 54 miles in one day.

She rode 6 times the  number of miles Caleb rode his bike.

Let Caleb rode b miles. It means,

54 = 6b

We can also find b as follows :

b = (54/6)

b = 9 miles

Hence, the required equation is "54 = 6b".

Help please I know what mean absolute deviation is I don’t know what it does tho
s344n2d4d5 [400]

Answer:

The average number of Tv's sold was higher at store A than at store B

Step-by-step explanation:

You don't have to solve anything. They already gave you the mean/average. They just want to know who sold the most, so in this case you would just see who has the higher number, and see what answer matches.
