Answer:
1. alternating interior angles
2. 60°
Step-by-step explanation:
1. By definition of <em>Alternating Interior Angles</em>, the angles must be located in between the parallel lines, and opposite of each other (hence alternating). The measurements of the two angles are exactly the same.
2. Since the angle measurements of Alternating Interior Angles are the same, x would = 60° as well.
~
The angles are 45° 60° and 75°
Elaboration：
Let the three angles be 3x 4x and 5x
( since the sum of interior angles of triangle=180° )
3x+4x+5x= 180
12x = 180
x = 15
3x= 45
4x= 60
5x= 75
