-9 = 1.1k + 3.5
-3.5 -3.5
-12.5 = 1.1k
/ 1.1 / 1.1
-11.4 = k
*IMPORTANT* This < means up words i just don't know how to write it

Answer:
-4
Step-by-step explanation:
Vertical angles are congruent, so
107=3x-4
3x=111
x=111/3=37°
Answer:
x²/2166784 +y²/2159989 = 1
Step-by-step explanation:
The relationship between the semi-axes and the eccentricity of an ellipse is ...
e = √(1 -b²/a²)
In order to write the desired equation we need to find 'b' from 'e' and 'a'.
__
<h3>semi-minor axis</h3>
Squaring the equation for eccentricity gives ...
e² = 1 -b²/a²
Solving for b², we have ...
b²/a² = 1 -e²
b² = a²(1 -e²)
<h3>ellipse equation</h3>
Using the given values, we find ...
b² = 1472²(1 -0.056²) = 2166784(0.996864) ≈ 2159989
The desired equation is ...
x²/2166784 +y²/2159989 = 1
