Question

Please help with number 14 I need the answer

Answer 1

As cd=de;

9x-25=6x+8

solve for X

replace the value of X into the other equations

Answer 2

see explanation

Explanation:

given the legs CD and DE are congruent , then

CD = DE , that is

9x - 25 = 6x + 8 ( subtract 6x from both sides )

3x - 25 = 8 ( add 25 to both sides )

3x = 33 ( divide both sides by 3 )

x = 11

Then

CD = 9x - 25 = 9(11) - 25 = 99 - 25 = 74

DE = 6x + 8 = 6(11) + 8 = 66 + 8 = 74

showing CD = DE

CE = 10x - 73 = 10(11) - 73 = 110 - 73 = 37
