The largest angle then is 108 degrees that is opposite the 3rd side which is the longest side and by using the cosine rule in trigonometry it is 37.77cm in length rounded to two decimal places

Find the third angle of a right triangle if the measure of on of the angles is 68?

The sum of interior angles of any triangle is 180 degrees. A right triangle is defined as a triangle having one angle that measures 90 degrees. Therefore, it follows that the sum of the remaining two angles will be 90 degrees 90-68=22 The third angle is 22 degrees


Can you have a right angled isosceles triangle?

Yes you can, by having other two angles of 45 degrees. 45+45+90=180. There are 180 degrees in a triangle.


What polygon has no parallel sides and all acute angles?

A triangle having all angles less than 90 degrees is a polygon having no parallel sides and all acute angles.


What are two angles having the same measurements?

This are called congruent angles. For example, In an isosceles triangle, the two angles which are opposite to the sides that have the same length, have the same measurements. They are called the base angles of the triangle. When each of them is 45 degree, the triangle is also a right triangle, since the other angle is 90 degree.


What is the angle of a triangle measuring 68 X 68 X 82?

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


Does a right triangle have an obtuse angle?

No, a right triangle must have a right angle (by definition). Because there is 180 degrees in a triangle and a right angle is 90 degrees, that leaves the remaining two angles having to equal 90 degrees. Therefore, a triangle cannot have an obtuse angle.


What does equiangular mean?

Equiangular means "having equal angles" or "with all angles equal" or the like. An equilateral triangle (a triangle having all 3 sides the same length) is equiangular. Each of it's interior angles is 60 degrees. A quadrilateral (a 4-sided figure) that is equiangular would have to have each of its interior angles equal to 90 degrees, and the quadrilateral would then have to be a rectangle.


How many diffrent parts does a triangle have that can be specified or measured?

Can a triangle have all three types of angles?

no The reason is because a triangle cannot have the sum of its angles exceeding 180 degrees. Having a right angle and an obtuse angle already puts the triangle at over 180 degrees because an obtuse angle must be over 90 degrees. Not to mention that this leaves no room for an acute angle.
