Question

Someone know the answer to this

Answer 1

Given:

in rectangle ABCD, BE = 3x + 5, AC = 40

To find:

X = ?

Solution:

AC = BD - Diagonal of rectangle are always equal

now BD = 40 units .....( i )

BE = ED, the diagonal of rectangle bisect each other in equal half

now, BD = BE + BD ...( ii )

BD = BE +BE from ..( ii )

40 = 2BE

BE = 20

3x + 5 = 20 ... from given

3x = 15

x= 5

Answer- The value of x is 5 units
