Answer:
C -2 or 1
Step-by-step explanation:
So from the equation you have x^2-x-1=-2*x+1
x^2-x-1+2*x-1=0
x^2 +x -2 =0
D= 1^2 -4*(-2)= 1+8=9
x = (-1+-3)/2
So x is either (-1+3)/2=2/2=1
or (-1-3)/2=-2
Answer:
relationship between base and hypotenuse is given cos angle
cos 20=b/h
cos20=x/160
x=cos20×160=150.35=150ft is your answer
