The answer to your question is:
Step-by-step explanation:
Data
x² + 8x = -4y - 8
x² + 8x + 16 = -4y - 8 + 16
x² + 8x + 16 = -4y + 8
(x + 4)² = -4(y - 2)
(x + 4)² = 4(-1)(y - 2)
Vertex = (-4, 2)
p = 1
Focus = (-4, 1)
Axis of symmetry x = -4
Directrix y = 3
Answer/Step-by-step explanation:
First, find the slope (m) of Line L using the points (0, 5) and (2, 1):

Slope (m) = -2
✔️Since the line is parallel bro Line L, it would also have the same slope value of -2.
We can use the slope (m) and a point (a, b) of the line to find its equation using the point-slope formula, y - b = m(x - a).
Substitute (a, b) = (3, 0), and m = -2 into y - b = m(x + a):
Thus,
✅y - 0 = -2(x + 3)
Rewrite equation in slope-intercept form
y = -2(x + 3)
✅y = -2x - 6
Answer:
Ratios are 2:3:5 given. So, 2*X+3*X+5*x=180° — sum of three angles of a triangle. So, X=18°. Hence angles are 36° , 54° and 90°
