Answer:
3. 30 degrees
4. 46 degrees
5. 55 degrees
Step-by-step explanation:
3. Let it be x
85+65+X=180
150 + x = 180
x = 180 - 150
x = 30 degrees
4. Let it be x
104 + 30 + x = 180
134 + x = 180
x = 180 - 134
x = 46 degrees
5. Let it be x
x + 85 + 40 = 180
x + 125 = 180
x = 55 degrees
PLEASE GIVE ME BRAINLIEST PLSSS
Because the focus is (-2,-2) and the directrix is y = -4, the vertex is (-2,-3).
Consider an arbitrary point (x,y) on the parabola.
The square of the distance between the focus and P is
(y+2)² + (x+2)²
The square of the distance from the point to the directrix is
(y+4)²
Therefore
(y+4)² = (y+2)² + (x+2)²
y² + 8y + 16 = y² + 4y + 4 + (x+2)²
4y = (x+2)² - 12
y = (1/4)(x+2)² - 3
Answer:
Answer:
The angles are 69.2 degrees and 20.8 degrees
Step-by-step explanation:
Complementary angles, when added together, = 90°
We’ll call the first unknown angle a and the second angle b
b = a - 48.4
a + b = 90
So let’s substitute in for b in the second equation:
a + a - 48.4 = 90
2a - 48.4 = 90
2a = 138.4
a = 69.2
69.2 - 48.4 = 20.8 = b
Now, does a + b = 90?
69.2 + 20.8 = 90
