Answer:
b=5 should be the correct answer
Answer:
The correct answer would be 36.
Step-by-step explanation:
It is B the only one that show proportionality
(x^2)/a^2+(y^2)/b^2=1
a>b
a=6, a^2=36
foci=(a^2-b^2)^(1/2)
4=(36-b^2)^(1/2)
16=36-b^2
b^2=36-16
b^2=20
b=2(5)^(1/2) or (20)^(1/2)
1=(x^2/36)+(y^2/20)
Answer:
132°
Step-by-step explanation:
180-48= 132°
since those angles lie on a straight line and are parallel
