Answer:
b = 4
, c = 8
Step-by-step explanation:
Using the sine ratio in the right triangle and the exact value
sin30° = 
, then
sin30° = 
= 
= ( cross- multiply )
c = 8
Using Pythagoras' identity in the right triangle
b² + 4² = 8²
b² + 16 = 64 ( subtract 16 from both sides )
b² = 48 ( take the square root of both sides )
b = 
= 
= 4
From the given information, the parabola is a sideways parabola facing left with vertex at the origin.
Required equation is (y - 0)^2 = 4p(x - 0)
y^2 = 4px
But 0 + p = -8 => p = -8
Therefore, required equation is y^2 = 4(-8)x
y^2 = -32x
