Carrie places a 12 foot ladder against a wall, if the ladder makes an angle of 57 degree with the level ground, how far up the wall is the top of the ladder

*face palms*

step-by-step explanation:

no

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.

just get this app called photo math it should be able to do those
