The sides of a triangle have lengths of x, x + 4, and 20. if the longest side is 20, which of the following values of x would make the triangle acute?
a. 8
b. 10
c. 12
d. 14

Consider that lines b and c are parallel. what is the value of x? what is the measure of the smaller angle?

Acomposition of transformations maps δxyz to δx"y"z". the first transformation for this composition is , and the second transformation is a 90° rotation about point x'.

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
