Step-by-step explanation:
Let the opposite interior angles be A and 2A.
In triangle sum of opposite interior angles =exterior angle
A+2A=135⁰
3A=135⁰
Α=45⁰,2A=90⁰
third angle=180⁰-(90⁰+45⁰)=45⁰
The angles of triangles are 45⁰,90⁰,45

Answer:
Let the opposite interior angles be A and 2A.
In triangle sum of opposite interior angles =exterior angle
A+2A=135⁰
3A=135⁰
Α=45⁰,2A=90⁰
third angle=180⁰-(90⁰+45⁰)=45⁰
The angles of triangles are 45⁰,90⁰,45⁰
