Question

ABCD is rectangle diagonal AC measure 2x+3 and diagonal BD measure 4x-21. find the value of x and measure of AC and BD

Answer 1

AS THE DIAGONALS OF A RECTANGLE ARE EQUAL.. SO,

2x+3=4x-21

3+21=4x-2x

2x=24

x=12

therefore, AC= 2X+3= 2*12+3=27

BD=4X-21=4*12+3=51

Answer 2

Answer:

Step-by-step explanation:

As per the diagonals of rectangle are equal.

So AC =2x + 3 and BD =4x - 21.

2x + 3 = 4x - 21

2x + 4x = - 21 - 3

6x = - 24

x =-24/6

X = - 4
