Answer:
∠ EAB = 85°
Step-by-step explanation:
∠ EBC and ∠ BCD are same- side interior angles and sum to 180° , so
∠ BCD = 180° - ∠ EBC = 180° - 148° = 32°
the sum of the 3 angles in Δ ADC = 180° , that is
∠ EDC + ∠ BCD + ∠ EAB = 180°
63° + 32° + ∠ EAB = 180°
95° + ∠ EAB = 180° ( subtract 95° from both sides )
∠ EAB = 85°
It would be 47/170 in the simplest form
The equation of the parabola with points (-1, 3), (0.5, 4.5) and (0,3) is y = 2x² + 2x + 3
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
The pareabola equation is in the form:
y = ax² + bx +c
At point (-1, 3):
3 = a(-1)² + b(-1) + c (1)
At point (0.5, 4.5):
4.5 = a(0.5)² + b(0.5) + c (2)
At point (0, 3):
3 = a(0)² + b(0) + c (3)
From the equations:
a = 2, b = 2, c= 3
The equation of the parabola with points (-1, 3), (0.5, 4.5) and (0,3) is y = 2x² + 2x + 3

Hey,I'm not sure enough...i guess if the highest power is 9 then we get 9 roots..sorryvif I'm wrong:')
