Hi!
An obtuse angle is one greater than 90 degrees, a right angle one that is 90, and acute less than 90.
An obtuse triangle is one with one obtuse angle, all the rest being acute. A right triangle is one with one right angle, all the rest acute. And finally, an acute triangle is one with three acute angles.
In this case, the angles measure 83 degrees, 31 degrees, and 66 degrees. All of them are acute angles, as they're all less than 90 degrees.
Therefore, the triangle is an acute triangle.
Hope this helped!

Hi!
For every 1 nanometre, there are 1e-9 metres. So, to convert 693.4 nanometres to metres, we multiply 693.4 by 1e-9.
<em>693.4 * 1e-9 = 6.934e-7.</em>
Hopefully, this helps! =)
