What line represents the relationship between r and s shown in the table

The third line

Step-by-step explanation:

This data table has a y-intercept of 10.  This is because it passes through the point (0, 10).

The rate of change is 1; this is because for every increase in x, the y-value increases by 1.  This makes the slope, rise/run, 1/1, or 1.

This means the line starts above 0 and increases.  The only graph that matches this is the third one.

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
