11. if corresponding sides of congruent triangles measure
(3 x - 4 )cm and (2x + 8 )cm what is the value of x

12.refer to item number 11 how long are the congruent sides?​


Sagot :

Answer:

1. 3x - 4 = 2x + 8

3x - 2x = 8 + 4

x = 12

2. 3x - 4 = 2x + 8

3(12) - 4 = 2(12) + 8

36 - 4 = 24 + 8

32 = 32

the two congruent sides measure 32 cm
