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!
Given:
The matrix multiplication
To find:
The order of resulting matrix.
Solution:
We know that, if order of first matrix is 
and the order of second matrix is 
, then the order of these two matrices is 
.
We have,
Here, the order of first matrix is 
and the order of the second matrix is 
. So, the order of the second matrix is 
. It is also written are 2 by 1.
Therefore, the correct option is A.
