Question

in a square ABCD AC is equal to 7 x minus 2 cm and BD is equal to 11 x minus 10 cm AC is equal to​

Answer 1

Answer:AC = 12

Step-by-step explanation:

7x-2=11x-10

Add 10 to both sides and get

7x+8=11x meaning 4x=8

Divide both sides by 2 and get your answer so 7×2=14-2=12

Answer 2

In Square ABCD,

AC = 7x - 2

BD = 11x - 10

In a square, diagonals are equal.

AC = BD

=> 7x - 2 = 11x - 10

=> 7x - 11x = -10 + 2

=> -4x = -8

=> x = 2

Then:

AC = 7x - 2

    = 14 - 2

    = 12 cm
