Answer:
30 degrees.
Step-by-step explanation:
The triangle's three angles add up to be 180 degrees. To find the other angle of the triangle, all you would have to do is 180 - (80 + 70) = 180 - 150 = 30. So, the last angle would be 30 degrees.
Hope this helps!
Answer:
30 Degrees
Step-by-step explanation:
what you would do is take 70 and 80 and add it up
then you would get 150
so then you would take 180 and 150 and subtract to get 30
That is how you get any missing degree for a triangle
Remember a triangle always equals up too 180 degrees
