It is an isosceles triangle having 3 interior angles 2 of which are equal in size and the 3 angles add up to 180 degrees.
Use Pythagoras' theorem to find its altitude and then use trigonometry to find the sizes of its angles.
The angles work out as 53 degrees, 53 degrees and 74 degrees

Using Pythagoras' theorem for a right angle triangle its hypotenuse is 82 units in length
Its supplementary angle is 82 degrees because 82+98 = 180 degrees
the supplement of an 82 degrees angle would be 98 degrees. To find the supplement of an angle, take the degrees of the angle you were given and subtract it from 180.
It is: 8 degrees because 82 degrees+8 degrees = 90 degrees
An obtuse angle.* * * * *The last time I checked, 82 was still considered to be less than 90. And in that case, it is an acute angle, not obtuse.
