Open in App

Solution

The correct option is **A** Obtuse angled

Given:

Scale : 1 cm = 1 in

Each of two angles of the

triangle = 33°

Third Side = 9 cm

Let the third angle of the triangle

be x°.

According to the angle sum property of triangles, we get:

x°+33°+33°=180°

⇒ x= 114°

Hence, the triangle will be an obtuse angled triangle.
