Question

Help I don’t understand this

Answer 1

y = 12.5

Explanation:

Notice these are similar triangles since they have angles of the same measure (congruent angles), then there must be a proportion among their sides such that:

`(y+5)/(5) =(14)/(4)`

therefore by cross-multiplying, we get:

4(y + 5) = 14 * 5

4 y + 20 = 70

4 y = 70 - 20

4 y = 50

y = 12.5
