Answer:
12
Step-by-step explanation:
15/5 = 3
4*3 = 12
d = 12
the hypotenuse is [tex]5^{2} + 4^{2} = c^{2}[/tex]
25+16 = [tex]c^{2}[/tex]
41=[tex]c^{2}[/tex]
[tex]\sqrt{41}[/tex]
In order to know the missing side u look at the smaller triangle first.
The two triangles are similar
The bottom side, 5(?)=15?
5(3)=15
Therefore you do the same to the other side of the missing
