Answer:
Step-by-step explanation
We have given that equation of line a+4b=0
⇒4b= -a
⇒
slope of line =
⇒ is negative therefore it lies into 4th quadrant
By, Pythagoras theorem
by putting value of P= -1 & B=4
the value of
with the given condition
i.e. ∈ (3π/2, 2π)
now,
The complete question in the attached figure
we know that
m∡4=65°
m∡4=m∡2---------> by internal alternate angles
m∡5=m∡3---------> by internal alternate angles
m∡1=180°-m∡2---------> 180°-65°--------> m∡1=115°
the answer is
m∡1=115°
