Question

please help answer this

Answer 1

Answer:

the missing length is 5

Step-by-step explanation:

Since we are given similar triangles, we can simply use proportions to solve the problem:

we say that 2 is to side of length 4, the same as m is to side lengths 10. And in math terms:

$\frac{2}{4} =\frac{m}{10} \\m=\frac{2*10}{4} \\m=\frac{20}{4} = 5$

Answer 2

5 because 4/2 is 2 and 10/2 is 5
