Multiply 20 by 5 and you get 100, please tell if this is what you wanted!
Y × 3 = 3 / 5
y = 3 / 5×3
y = 3/15
y = 1/5
In short, Your Answer would be 1/5
Hope this helps!
Answer:
x = 
Step-by-step explanation:
The altitude of the triangle must equal 4 because it is a right triangle with another leg of 3 and a hypotenuse of 5 (reason is due to the pythagorean theorem)

= 
16 + 49 = 
65 = 
x = sq rt 65
