Answer:
121°
Step-by-step explanation:
Sum of angles in a pentagon = ( n-2) 180
(5-2)180
=3x180
=540°
X+87+92+105+135=540
X+419=540
X=540-419
X=121°
24040.625
Hope this helped! I'm not good at explaining the steps, but this is the answer.
the answer is k=4.6. hope this helps
f(5) = 9
Do this by substitution:
f(x) = 4x - 11
f(5) = 4(5) - 11
f(5) = 20 - 11
