Angle K = angle M
(4x-1)=(2x+27)
4x-2x=27+1
2x=28
x=14
K=4x-1 then 4(14)-1
55 degrees
M=2x+27 then 2(14) +27
55 degrees
K+M+L =180
55+55+L=180
110+L=180
L=70 degrees
Therefore K=55 degrees M=55 degrees L=70 degrees
Answer:
3
Step-by-step explanation:
the perpendicular slope is the negative reciprocal.
-1 divided by -1/3 = 3
check the picture below.
now, if we split that triangle like so with that red line, we can use the right-triangle there, to get θ.

Answer:
it looks like an acute angle
