Question

Find the values of the variable and the lengths of the sides. ​

Answer 1

See answers below

Explanation:

2x - 7 = x + 1 sides are equal

x - 7 = 1

x = 8

Find the length of each side

AD = 2x -7 BC = x + 1 AB = 2x - 2 DC = x - 1

AD = 2(8) - 7 BC = 8 + 1 AB = 2(8) - 2 DC = 8 - 1

AD = 16 - 7 BC = 9 AB = 16 - 2 DC = 7

AD = 9 AB = 14
