Question

DEFG Is a rectangle. DF=5x-5 and EG=x+11. find the value of x and the length of each diagonal. (Draw and label the sketch below)

Answer 1

df=eg x=4

Answer 2

DF and EG are diagonals. Diagonals in a rectangle are always equal to each other, so we can set 5x-5=x+11

add 5 to both sides

5x=x+16

subtract x from both sides

4x=16

divide both sides by 4

x=4
