If the sides are 10 cm by x cm by x-2 cm opposite to angle 60 degrees then by substituting the given values into the cosine rule a^2 = b^2 +c^2 -(2bc*cosine A) the value of x works out as 16
A triangle with no congruent sides is called a scalene triangle. If it has a 95-degree angle, the other two angles must be less than 85 degrees each since the sum of all angles in a triangle is 180 degrees. The lengths of the sides will vary, with the longest side opposite the largest angle, which in this case is 95 degrees. Therefore, the triangle will have all sides of different lengths corresponding to its angle measurements.
The largest angle of the triangle will be opposite its largest side and by using the Cosine Rule it works out as 106.23 degrees.
An isosceles triangle has a total of 180 degrees, just like any triangle. In an isosceles triangle, two sides are of equal length, which means the angles opposite those sides are also equal. Therefore, if you know the measure of one of the equal angles, you can calculate the third angle by subtracting twice that angle from 180 degrees.
The smallest angle will be opposite the smallest side of the triangle and so by using the cosine rule it works out as 43.84 degrees.

Given the reference perspective of a specific angle the sides are are the adjacent sides and the opposite side If we have a right triangle the longest side (opposite the right angle) is the hypotenuse.
Their opposite angle are equal and all 3 angles will add up to 180 degrees
A triangle with two congruent sides is isosceles. A triangle with an angle of 104 degrees is obtuse. So you would have an obtuse isosceles triangle.
The only triangle that has a hypotenuse is a right-triangle. The hypotenuse is the side opposite the right angle, so the angle is always 90 degrees. In this case, if you're just finding the angle then you don't need to know what the side lengths are.
An isosceles triangle has a total of 180 degrees, just like any triangle. In an isosceles triangle, two sides are of equal length, which means the angles opposite those sides are also equal. Therefore, if you know the measure of one of the equal angles, you can calculate the third angle by subtracting twice that angle from 180 degrees.
The smallest angle will be opposite the smallest side of the triangle and so by using the cosine rule it works out as 43.84 degrees.
No, a right angled triangle cannot have three acute angles because an acute angle is less than 90 degrees and a right angled triangle has one angle of exactly 90 degrees (which is what right angled means, equal to 90 degrees).Also, because the triangle has a right angle (of 90 degrees) it cannot have three equal sides; it can have two equal sides but the side opposite to the right angle (the hypotenuse) will always be longer than either of the other two sides.

In a triangle, each angle is opposite to one side. The size of the angle is related to the length of the side opposite to it; larger angles correspond to longer sides. Thus, each of the three angles in a triangle is uniquely associated with one of the triangle's three sides.
