P = 180 - (92+51)
p = 180 - 143
p = 37
D is what i got. because that is the only possible answer.
The standard form equation of the hyperbola:
x² / a² - y² / b² = 1
a = 5,
a² = 25
c = 6
c² = a² + b²
36 = 25 + b²
b² = 36 - 25
b² = 11
Answer:
x²/25 - y²/11 = 1
I think the best answer is (-5x)+6y=36
Area of the shaded part is given by:
A=(area of the sector)-(area of triangle)
A=(θ/360πr²)-(1/2sinθab)
A=(120/360*π*6²)-(0.5*6²*sin120)
A=12π-15.59
A=22.1 cm²
Answer: A=22.1 cm²
