ΔABC is a right triangle
By the Pythagorean theorem:
AC = √(BC² - AB²) =√(5²-3²) = √(25-9) = √16 = 4
ΔBED is a right triangle
DE = 4
BE = AB + AE = 3 + 4 = 7
By the Pythagorean theorem:
BD = √(BE² + DE²) =√(7²+4²) = √(49+16) = √65
Answer: BD = √65
This is an inscribed quadrilateral. The opposite angles are supplementary. They add to 180 degrees.
angleB + angleD = 180
93 + x+30 = 180
x+123 = 180
x+123 = 180-123
x = 57

ANSWER

EXPLANATION
The given parabola has directrix x=2.
This implies that, the parabola is opens in the direction of the negative x-axis because it must open in a negative direction to the directrix.
The equation of such parabola is of the form:

where (h,k)=(-5,8) is the vertex.


But the parabola opens to the left.
p=-7
The equation now becomes
