How do you find the other side of an obtuse triangle given 2 sides and 1 angle?

We use the law of cosine:
c^2 = a^2 + b^2 - 2abcosC
This means that we know the sides a and b, and the angle C between them.

How do you classify a triangle by its angles?
If all three angles of a triangle measure less that 90 degrees (if all three angles are acute), the triangle is an acute triangle. A triangle that has a right angle (an angle the measures exactly 90 degrees) is a right triangle. (The other 2 angles will be acute angles.) A triangle that has an angle that is greater than 90 degrees (an obtuse angle), is an obtuse triangle. (The other 2 angles will be acute angles.)
If a triangle has one obtuse angle then the other two angles are acute?
Yeah, they have to be. The sum of the interior angles of a triangle is always 180. If one angle is greater than 90, then the remaining two's sum cannot be.
Is it possible to draw a reflex angle so the other angle formed by the arm is obtuse?
yes. if the reflex angle is 260 degrees, the other is 100 which is obtuse
Classify the triangle with sides 10 13 19 as acute right or obtuse?
In a right triangle, a2 + b2 = c2, where c is the longest side. If the square of the longest side is more than the sum of the other two squares, the triangle has an obtuse angle. If it is less, all angles are acute.
If the square of the length of the longest side of a triangle is greater than the sum of the squares of the lengths of the other two sides of what kind of triangle?
It would be an obtuse triangle with one angle being greater than 90 degrees.
Is an obtuse triangle a right triangle?
its a triangle * * * * * No, it an obtuse triangle is not a right angle triangle. An obtuse angled triangle has one angle which is greater than 90 degrees and the other two are acute. In a right angled triangle, the largest angle is 90 degrees while the other two are acute. So one cannot be the other.
Can a Triangle contain a right angle and a obtuse angle?
No because it only has a Right angle. It doesn't have an Obtuse angle, or other angles.
How many obtuse angles are there in a obtuse triangle?
There is one obtuse angle, and the other two are acute angle because in all the whole triangle is 180 degrees.
Can a triangle with a obtuse angle have two acute angles?
Yes. A triangle can have only one obtuse angle. The other two angles will always be acute.
Is a triangle a Acute Angle Obtuse Angle Right Angle?
A triangle is not an angle. A triangle is made of three angles. -- All three of them can be acute, but they don't need to be. -- One of them can be obtuse but doesn't need to be. -- One of them can be a right angle but doesn't need to be. -- If any angle in the triangle is right or obtuse, then the other two need to be acute.
Does obtuse triangle have a right angle?
No, an obtuse triangle cannot have a right triangle for the reason that an obtuse angle is greater than 90 degrees; therefore, the other two angles must be lower than 90 degrees.
What is a triangle contanining one obtuse angle?
If the other two acute angles are of different sizes then it is an obtuse or a scalene triangle.
Use obtuse triangle in a sentence?
In an obtuse triangle, one angle is obtuse and the other two are acute. "The buildings are arranged in an obtuse triangle and occupy most of the long, thin parcel of land."
Can one of the internal angles of a triangle be an obtuse angle?
yes, there can be an obtuse internal angle in a triangle, but keep in mind that the other two angles' sums plus the obtuse angle can only equal 180 degrees (meaning that the other non-obtuse angles will be very small acute angles)
How do you draw an obtuse scalene triangle?
One angle must be an obtuse angle and the other two angles must be acute angles
How do you find the angles of a right angle triangle with one side is 300mm the other is 4200mm i need to know the obtuse angle?
If it's a right angle triangle then you'll have difficulty in finding the obtuse angle because it will not have one.
What is a triangle that has exactly one obtuse angle?
It could be an isosceles triangle providing that the other 2 acute angles are equal otherwise it is just an obtuse triangle
