So it would be x12 to the 2nd power, kinda hard to explain but i really hope this helped
Since one side is 40°, you subtract that from 180.
180° - 40°= 140°.
So therefore your missing side lengths are 140, 40, and 140.
hopefully this helps
1.5, 2.25, 3.375, 5.0625, 7.59375... and so on
Subtract 8 from both sides and then multiply both sides by -5
V = -5
14720 is answer. or product
