Find the size of angle x.
Х
65
35

Step-by-step explanation:
or,180°=65°+35°+x
or, 180°=100°+x
or,180°-100°=x
therefore, x=80°
Answer:
80 degrees
Step-by-step explanation:
The total angle measure of a triangle, no matter the type, is always 180 degrees.
Using this, we can calculate the missing angle:
[tex]180=65+35+x[/tex]
[tex]x=180-(65+35)[/tex]
[tex]x=180-100[/tex]
[tex]x=80[/tex]
