The sides of a triangle are produced in order. The sum of the three exterior angles so formed is :-

 

 

 

 

In the figure, chord $BC$ is extended to $P$. Tangent from $P$ to the circle is $PA$. $AQ$ is the bisector of $\angle BAC$. If $\angle PAC=x$ and $\angle PCA=y$, then prove that $\angle BAC=y–x$.

In the figure, chord $BC$ is extended to $P$. Tangent from $P$ to the circle is $PA$. $AQ$ is the bisector of $\angle BAC$. Prove that $\angle PAQ=\frac{y+x}{2}$

In Figure, the values of $x$ and $y$ are

In Figure, the value of $x$ is

In Figure, if $AB\left|\right|CD$, the values of $x$ and $y$ are

In figure, bisector of $\angle BAC$ intersects side $BC$ at point $D$. Prove that $AB>BD$.

In a triangle, an exterior angle at a vertex is $95°$ and it's one of the interior opposite angles is $55°$. Find all the angles of the triangle.

Compute all angles of the figure below:

In the given figure, find the values of $x$ and $y$.

In Figure, the values of $x$ and $y$ are

Two angles of a triangle are$40°$and $60°$.Calculate all its outer angles.
