Answer:
35
Step-by-step explanation:
You have to divide 280 by 8 and that's how you get it.
First of all you need to get rid of the -27 on the left side, to do so you add 27 to both sides so it becomes:
5/8a=20
Now you can divide it by 5 to get:
1/8a=4
Now multiply it by 8 to get:
a=32
Hope this helps :)
20^2=10^2+2√39^2
400=100+12.49
400=112.49
means c^2>a^2+b^2
so the answer is an obtuse triangle
