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, 
Answer:
3. 10 - 5 is 5. so that is the difference. difference means subtraction.
4. 108 - 30 = 78. so she can move 78 degrees miore after therapy because 108 minues 30 is 78
5. 99 because 180 - 81 = 99. there is always 180 degrees in a line angle.
6. 130 degrees. 25 + 25 = 50 so 180 minus 50 equals 130

j) the angle bisector U
Step-by-step explanation:
The area of a circle is A = πr^2. We let A1 And A2 the areas of the circles and r1 and r2 the radius of each, respectivley.
A1 + A2 = 80π
Substitute the formula for the area,
π(r1)^2 + π (r2)^2 = 80π
From the statement, we know that r2=2(r1).
<span>π(r1)^2 + π (2 x r1)^2 = 80π
</span>We can cancel π, we will have
5 x (r1)^2 = 80
Thus,
r1 = 4 and r2 = 8
