Answer:
y
Step-by-step explanation:
In the figure Altitude of the hypotenuse AC divides the right triangle into two triangles, that are similar to each other
triangle ABC is similar to triangle ACD
WE make a proportion using the sides of the similar triangles
AD/ AB= AC/ CD
[tex]\frac{a}{b} = \frac{y}{h}[/tex]
So missing term in the proportion is 'y'
To complete the proportion we use 'y'
