A triangle can have two obtuse angles.

Each angle of a triangle can be $60°$.

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

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

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

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 angle triangle are in the ratio $2:3$. Find the angles of the triangle.

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