Step-by-step explanation:
what is the question
Answer: 25
Assuming the dotted line touches the middle of the base of the triangle,
Using Pythagoras Theorem,
(30/2)^2 + (20)^2 = x^2
x^2 = (15)^2 + 400
x^2 = 625
x = √625 or -(√625)
x = 25 or -25
But since x needs to be a positive value,
x = 25
0.505 means 505 * 0.001, or 505 * 1/1000. This is equivalent to 505/1000, or 101/200.
