Answer 2

Answer:

1. triangle sides 40, 40, 40, 2. triangle sides 6.1, 6.1, 7.5

Step-by-step explanation:

1.   In first triangle 3 side are equal ⇒ 5y = 3y+16

                                                        ⇒ 5y - 3y = 16

                                                           2y = 16

                                                             y = 8

 length of the sides  = 5y = 5 (8) = 40

                                   3y+ 16 = 3 (8) +16 =40

   3 sides of triangle 40, 40, 40

 2.  in 2nd triangle 2 sides are equal  2x+1.5 =x+3.8

                                                              x = 2.3

 side of the triangle are  2 (2.3 ) + 1.5 = 4.6+1.5= 6.1

                                          3 (2.3) +0.4= 6.9 +0.6= 7.5
