Answer:
obtuse
Step-by-step explanation:
An angle supplementary to 60 or 69 degrees would be 180-60 or 180-69.
If we were to calculate that, the number would be over 90 degrees. 180-60=120. 180-69=111. Thats above 90 degrees. Angles over 90 degrees are obtuse
3/10
2/5 + x = 7/10
x = 7/10 - 2/5
x = 7/10 - 4/10
x = 3/10
Hope this helps :)
