Answer:
true
Step-by-step explanation:
The measure of the interior angles would be 120°, and they would all add up to be 720°
Answer:
y = 3
Step-by-step explanation:
The vertex of the parabola is (1,4) and the axis of the parabola is parallel to the positive y-axis.
So, the equation of the parabola will be (x - 1)² = 4a(y - 4) ....... (1)
Now, we have to get the value of a since the equation id the directrix is y = 4 - a.
Now, the parabola passes through the point (3,5) {Obtained from the graph).
Therefore, from equation (1), we get, 2² = 4a × 1, ⇒a = 1
Therefore, the equation of the directrix is y = 4 - 1 = 3. (Answer)
b = 78°
The angles at a point sum to 360°
that is 45 + 237 + b = 360
282 + b = 360 ( subtract 282 from both sides )
b = 360 - 282 = 78°
