All the angles of a triangle add up to 180 degrees.
30+39+<4= 180
69+<4= 180
Subtract 69 on both sides.
<4= 111 degrees
<1 and <4 are supplementary and adjacent. They equal 180 degrees as well.
111+<1= 180
<1= 69 degrees
I hope this helps!

5) since (x-a)^2+(y-b)^2=r^2
plug in (-5,2) as (a,b) and r=3
Making the equation:
(x+5)^2+(y-2)^2=9
6) (x-0)^2+(y-0)^2=r^2
since we have (0,5)
0^2+5^2=r^2
Final equation: x^2+y^2=25

Answer:
y=-2x-3
Step-by-step explanation:
4x+2y=-6
2y=-6-4x
y=-6/2-4/2x
y=-3-2x
y=-2x-3
