In triangle $XYZ,$ $\angle Y = 45^\circ$ and $\angle Z = 60^\circ.$ If $XZ = 4,$ then what is $XY$? [asy] unitsize(3 cm); pair X, Y, Z; X = (0,1); Y = (-1,0); Z = (1/sqrt(3),0); draw(X--Y--Z--cycle); label("$45^\circ$", Y + (0.3,0.1), fontsize(10)); label("$60^\circ$", Z + (-0.2,0.1), fontsize(10)); label("$X$", X, N); label("$Y$", Y, SW); label("$Z$", Z, SE); label("$4$", (X + Z)/2, NE); [/asy]

Two lines parallel to a third line are parallel to each other. always sometimes or never

The speed of a falling object increases at a constant rate as time increases since the object was dropped. which graph could represent the relationship betweent time in seconds, and s, speed in meters per second? speed of a falling object object over time

20 points 1. your friend, taylor, missed class today and needs some identifying solutions to systems. explain to taylor how to find the solution(s) of any system using its graph. 2. taylor graphs the system below on her graphing calculator and decides that f(x)=g(x) at x=0, x=1, and x=3. provide taylor some feedback that explains which part of her answer is incorrect and why it is incorrect. f(x)=2x+1 g(x)=2x^2+1
