All three angles on a triangle always equal 180°.
Example: 100°+40°+40°=180°

102+39=141°
180-141=39°
x = 39°

When you add up all the angles it should equal to 180 so 180-102=78 then 78-39=39 so x=39

Answer:

$g(x)=(x+4)^2-5$

Step-by-step explanation:

g(x) is shifted 5 down in the y axis, meaning you have to subtract 5 from the function, and is shifted 4 to the left in the x axis- meaning you have to add to the x's in the function.
