Mathematics
1 answer:
REY [17]3 years ago
4 0

Answer:

y = 8

Step-by-step explanation:

Since the 2 triangles are similar then the ratio of corresponding sides are equal, that is the sides 15 and 10 and y + 4 and y, thus

\frac{15}{10} = \frac{y+4}{y} ( cross- multiply )

10(y + 4) = 15y ← distribute left side

10y + 40 = 15y ( subtract 10y from both sides )

40 = 5y ( divide both sides by 5 )

8 = y
