*10. Find the length of AD

Answer 1

Lines AG and GC are the same.

Angle D is the same on both sides.

This means that line AD and DC are the same.

Set these equal to each other and solve.

2x -3 = x + 2

Add 3 to both sides:

2x = x + 5

Subtract x from both sides:

X = 5

Now you have a value for x, solve for the length.

AD = 2(5)-3 = 10-3 = 7

AD = 7
