As we know that the sum of all angles of a triangle is 180°.
So, here we will apply this knowledge.
[tex]115\°+12\°+x\°=180\°[/tex]
[tex]127\°+x\°=180\°[/tex]
Now, we will subtract 127° from both sides of the equation, and we get;
[tex]x\°=180\°-127\°[/tex]
[tex]x\°=53\°[/tex]
Therefore,[tex]x=53.[/tex]
The value of x° is 53°.
Hence, the third angle in the given triangle is 53°.
What is a triangle?
A triangle is a 3-sided polygon sometimes (but not very commonly) called the trigon. Every triangle has three sides and three angles, some of which may be the same.
What is called triangle?
A triangle is a closed, 2-dimensional shape with 3 sides, 3 angles, and 3 vertices. A triangle is also a polygon. The above figure is a triangle denoted as △ABC. Examples of Triangles. Some real-life examples of triangles include sandwiches, traffic signs, cloth hangers, and a rack in billiards.
What are the parts of a triangle?
All triangles have three sides and three corners (angles). The point where two sides of a triangle meet is called a vertex. The base of a triangle can be any one of its three sides, but it is usually the bottom one.
