Answer:
a=-8 b=2
Step-by-step explanation:
x^2+6x-16
x^2+(8-2)x-16=0
x^2+8x-2x-16=0
X(X+8)-2(X+8)=0
(X+8)(x-2)=0
Compare with (X+a)(X+b)
Where we get a=-8 b=2
if you divide a number by 2 then you would probably end up with a whole number but if you divide a number by 1/2 you will end up with a fraction

Answer:
b= {1,2,3,4} is the answer
For a right triangle, we have he advantage of using the trigonometric functions like cosine and sine.
If you use cosine function:
cos45 = adjacent/hypotenuse
cos 45 = b/c
c = b/cos 45
If you use sine function:
sin 45 = opposite/hypotenuse
sin 45 = a/c
c = a/sin45
From the choices, the answer is <span>b over cos 45 degrees</span>
