We can use two different methods to find our missing angle:
Subtract the two known angles from 180° :
Plug the two angles into the formula and use algebra: a + b + c = 180°
Answer c would be the answer hope it helps
Step-by-step ex planation:
point slope form:y-2=4(x+1)
then distribute 4 and simplify y-2=4x+4 , y=4x+6 is the slope -y intercept form
then, move 4x on the left side, you get -4x+y=6 , multiply every term by -1, you get 4x-y=-6 which is standard form.
