Yes by means of trigonometry.
The sine, cosine, or tangent of the known acute angle
tells you the ratio of two of the sides. You can easily
arrange things so that one of them is the side you know.
The rest is just arithmetic and Pythagoras.
If those are the lengths of the triangle's sides, then you have a "right" triangle. The angle opposite the 5-inch side is a 90-degree angle.
It is an isosceles triangle because the third angle must measure 50 degrees
45 degree
Triangles measure 180 degrees. A triangle that has one 90 degree angle is known as a right triangle.
80 degrees(We're talking strictly about interior angles here.)
37 degree
You can measure it. Or you can measure some other quantities (for examples, the lengths of the sides of a triangle), and calculate the angle using trigonometry.
I cut out the lengths to have a visual look at the problem and the answer is NO you cannot arrange 5cm, 12cm, and 19cm into a triangle. Even straightening out the lengths of 5cm and 12cm into a 180 degree angle will not measure out to the 19cm. You cannot have a side that is more than the length of the other two sides combined in a triangle.
If those are the lengths of the triangle's sides, then you have a "right" triangle. The angle opposite the 5-inch side is a 90-degree angle.
It would be an acute-angled triangle, but it's missing a degree!
no it doesn't matter what size an equalateral triangle is, it still has 60 degree angles
no because an equilateral triangle is a total of 180 degrees not 120. but if you need to find the missing angle or missing degree then yes!
since it is a right triangle there is one 90 degree angle and another of the angles is 45 degrees. there is 180 degrees in a triangle so the missing angle is 45 degrees.
The measure of only one angle and one side is not sufficient to calculate the lengths of the sides of a triangle. If you have one more angle or one more side you can use the sine rule.
A degree is a measure of an angle (in geometry), a triangle is a 2-dimensional object. So the question makes no sense.
A right angle
the missing angle is 93 degrees. you find that out by adding 53 and 34 and then subtracting them from 180. :)
