Answer:

x = 30°
DB = 26
AD = BC = AB = DC = 7

Step-by-step explanation:

<em>Diagonals of a square are congruent and perpendicular and bisect each other</em>

m∠AEB = 3x

m∠AEB = 90°

3x = 90° ⇒ x = 30°

AE = 3x - 2

EC = 2x + 3

AE = EC
3x - 2 = 2x + 3
3x - 2x = 3 + 2
x = 5

DB = EC = 2(AE) = 2(3*5 - 2) = 2(13) = 26

<u>AD and BC are the sides, which are equal</u>

2x - 1 = 5x - 13
5x - 2x = 13 - 1
3x = 12
x = 4

AD = BC = AB = DC = 2*4 - 1 = 7

I need help, I dont know how to convert ratios into decimals and percentages [EX: write the ratio 5 to 8 in a decimal/percent]

Fractions are just unsimplified numbers. For example 5/8 is just 5 divided by 8 so 0.625. To find the percent from that you move the decimal two places to the right making it 62.5%. Hope this helps!
