It means that you have to find the solution of the systems of equations.
Steb by step:
3x + x +20 + 32 =180°
4x +52 = 180°
-52 from both sides
4x = 128
divide both sides by 4
x = 32°

Answer:
We were given the equation of a rainbow, which follows a parabolic path, which is
By comparing to the vertex form,
We have the vertex at (h,k)=(1,6)
Since a=-0.1<0, the parabola opens down.
At y-intercept, x=0.
