Answer:
Step-by-step explanation:
Let us write the equations in standard form:
We have
and
Since the eccentricity of this conic is less than 1, the conic represents an ellipse.
The second equation is 
.
This is a hyperbola, because eccentricity is more than 1.
The third equation is 
.
This is a parabola, because eccentricity is 1.
The fourth equation is 
.
This is also a hyperbola, because eccentricity is more than 1.
Answer: angle ITU = 145 degrees
===============================================
Explanation:
Angle STU is the largest angle composed of the smaller angles STI and ITU.
In other words, the two smaller angles add up to the larger one.
(angle STI) + (angle ITU) = angle STU
( 20 ) + ( 12x+1 ) = 13x + 9
20+12x+1 = 13x+9
12x+21 = 13x+9
21-9 = 13x-12x
12 = x
x = 12
Using this x value, we find that,
angle ITU = 12x+1 = 12(12)+1 = 145 degrees
----------
As a side note,
angle STU = 13x+9 = 13(12)+9 = 165 degrees
This is confirmed with
(angle STI) + (angle ITU) = (20) + (145) = 165 = angle STU
