Find the value of X in the isosceles triangle shown below

x = 2

Step-by-step explanation:

Use Pythagerean Theorem:

x ^2 + 4^2 = (square root 20)^2

x^2 + 16 = 20

x ^2 = 4

x = 2

the answer is d

step-by-step explanation:

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.
