Please help solve this problem
irina1246 [14]

Answer:

y = 15

Step-by-step explanation:

The triangles follow a scale factor. This scale factor can enlarge or make a triangle smaller, using this factor, like a ratio. We can do 22/10 to get this scale factor for the set, which is 2.2. Finally, divide 33 by 2.2 to get 15 for the missing side length y.

Answer:

\boxed{y = 3}

Step-by-step explanation:

=  > \frac{5 - 7y}{2 + 4y}  =  -  \frac{8}{7}  \\  \\  =  > 7(5 - 7y) =  - 8(2 + 4y) \\  \\  =  > (7 \times 5) - (7 \times 7y) = ( - 8 \times 2) + ( - 8 \times 4y) \\  \\  =  > 35 - 49y =  - 16  - 32y \\  \\  =  > 35 - 49y + 32y =  - 16 \\  \\  =  > 35 - 17y =  - 16 \\  \\  =  - 17y =  - 16 - 35 \\  \\  =  >   \cancel{- }17y =  \cancel{- } 51 \\  \\  =  > 17y = 51 \\  \\  =  > y =  \frac{51}{17}  \\  \\  =  > y = 3
