We can see that the triangle is given as one of the angles is 90 degrees . The triangle is a right-angle triangle, and scalene also.
A right-angled triangle is a triangle having one of its angles with measure of 90°
The slanted side of that triangle is called Hypotenuse and it is the longest side in that triangle.
We can see that the triangle is given as one of the angles is 90 degrees and the other two angles are 36 and 54 degrees.
If one of the angles is 90° then the triangle is a right-angled triangle.
Also, the length of the two sides is given as 8.66 units and 5.1.
We have already concluded that the triangle is a right-angle triangle, so all the three sides of the triangle must be different.
This implies that the triangle is scalene also.
