Telangana Board Solutions for Chapter: Triangle and its Properties, Exercise 8: Exercise - 3

The angles of a triangle are in the ratio $1 : 2 : 3$. Find the angles.

In the figure, $\overline{DE}\parallel \overline{BC}$, $\angle A=30°$ and $\angle B=50°$. Find the values of $x$, $y$ and $z$.

In the figure, $\angle ABD=3\angle DAB$ and $\angle BDC=96°$. If $\angle ABD=k°$.

In $△PQR$, $\angle P= 2\angle Q$ and $2\angle R = 3\angle Q$, calculate the angles of $△PQR$.

If the angles of a triangle are in the ratio $1 : 4 : 5$, find the angles.

The acute angles of a right triangle are in the ratio $2 : 3$. Find the angles of the triangle.

In the figure, $△PQR$ is right-angled at $Q$, $ML\parallel RQ$ and $\angle LMR=130°$. Find $\angle LPM, \angle PML$ and $\angle PRQ$.
