My grades just dropped my moms mad and everythings falling. My percentage grade went from 98 to 33. Im down bad now, im grounded too for i dont know how long. I didnt do a assignment and it was worth 50 pervent of my grade. Im just asking myself what to do any advice

you need to show the graph

step-by-step explanation:

where are the choices?

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.
