No. Assuming that you have followed the conventional labelling of sides, cot(A) = sqrt(91)/3.

Can an obtuse triangle be an right triangle?
No an obtuse triangle cant be a right angle because,a right angle is 90 degrees. a obtuse triangle is over 90 degrees
Why is a right obtuse triangle not possible?
because if it is obtuse, there is no right angle. each corner has to be over 90 degrees (a right angle) to be an obtuse triangle.
When you say Tangent of 30 equals -6.40 does the -6.40 represent the length or angle of something else?
In a right triangle, the tangent of an angle other than the right angle is the ratio of the length of the side opposite the angle over the length of the side adjacent to the angle (the side between the angle and the right angle).
The hypotenuse of a right triangle is a side opposite the?
The hypotenuse of a right (angled) triangle is the side opposite the right (90 degree) angle. The hypotenuse is also the longest side.The hypotenuse of a right triangle is the side opposite theThe sine of an angle is the side opposite over the hypotenuse of the triangle.
Can you work out the area of any triangle using bxh divided by 2?
Yes, that works for any triangle. The height always has to be at a right angle to the base. If there is an angle over 90 degrees, you may have to extend the base.Yes, that works for any triangle.

Is a right triangle an obtuse angle?
Certainly not, if you measure a right angled triangle the it comes to 90 degrees you only get an obtuse angle if you have OVER 90 degrees.
Why construction of a triangle with right angle and another obtuse angle is not possible?
Because the 3 interior angles of a triangle add up to 180 degrees no more and no less but a right angle plus an obtuse angle would be over 180 degrees.
Explain Why can't a right triangle can't have an obtuse angle in it?
Because the 3 angles in a right angle triangle add up to 180 degrees and if an obtuse angle was included then they would add up to over 189 degrees.
A triangle with one angle over 90 degrees?
A triangle with one angle over 90 degrees is an obtuse triangle.
In trig what is the opposite side over the hypotenuse?
It is the 'sine' ratio for a right angle triangle
Is it possible for a right triangle to have two right angles why or why not?
No because the 3 angles in right angle triangle add up to 180 degrees and so 2 right angles plus another angle would be over 180 degrees.
Why can't a triangle cannot have one right angle and one obtuse angle?
Because a triangle has 3 interior angles that total up to 180 degrees but an obtuse and a right angle are 2 angles which add up to over 180 degrees.
