Answer:
AA criterion
a/x = c/a
a² = cx
b/(c - x) =c/b
b² = c(c - x)
a² + b² =cx + c(c - x) = c²
a² + b² = c²
Step-by-step explanation:
Answer:
b = 12 = 20.78
c = 24
Step-by-step explanation:
The sides of a 30-60-90 triangle always have the same proportion to each other. The side opposite the 30 degree angle is x, the side opposite the 60 degree angle is x and the side opposite the 90 degree angle is 2x (this side is called the hypotenuse) .
Since we know the side opposite the 30 degree angle here is 12, then we know that the side opposite the 90 degree angle is 2 times the side opposite the 30 degree angle, c = 24 units (2 x 12).
Finally, the side opposite the 60 degree angle is 12 which equals 20.78 units.
Answer:
D
Step-by-step explanation:
Any ellipse has the following equ
ation:
where
- 2b = vertical axis length
- 2a = horizontal axis length
(as in the picture)
So it should be like:
Since it should be moved to the right and up, the answer would be:
Answer:
4
Step-by-step explanation:
25+25=50
50*2=100
100/25=4
