Answer:
x = 47
Step-by-step explanation:
Every triangle's interior angles add up to 180°.
Let's make an equation.
x + 102 + 31 = 180
x + 133 = 180
x = 47
For a hyperbola

where

the directrix is the line

and the focus is at (0, c).
Here, we have c = 5, a² = 9, so b² = 5² - 9 = 16.
a = √9 = 3
b = √16 = 4
Your hyperbola's constants are ...
a = 3
b = 4
______
Please note that the equation of a hyperbola has a negative sign for one of the terms. The equation given in your problem statement is that of an ellipse.
Answer:
12%
.12
Step-by-step explanation:
3/25 * 4/4 = 12/100
We know that out of 100 means percent
12%
Since it is over 100, move the decimal 2 places to the left
.12
X= -2.8596 or rounded up -2.86 is the correct answer.
