There is no ones place after the decimal so 3 is in the tenth place, so 2.4
Answer:
79°
Step-by-step explanation:
Angle one is an alternate exterior angle to the angle that has 79° in it so angle one will equal 79°.
In this problem, given the focus at (2,4) and directrix at y = 8. then it is implied that the parabola is facing downwards. The vertex hence is at the middle of the focus and the directrix, hence at (2, 6). The general formula of the parabola is y-k = -4a ( x-h)^2. Substituting, y -6 = -1/8 *(x-2)^2. Answer is A.
