List of top Mathematics Questions on Trigonometric Ratios of Some Specific Angles asked in TS POLYCET

The value of \(2\tan^2 45^\circ + \cos^2 30^\circ - \sin^2 60^\circ\) is \dots
In \( \triangle ABC \), \( DE \parallel BC \), if \( AD = x + 1 \), \( DB = 3x - 1 \), \( AE = x \), and \( EC = 4x - 3 \), then the value of \( x \) is:
In \( \triangle ABC \), \( DE \) is a line such that \( \frac{AD}{DB} = \frac{AE}{EC} \) and \( \angle EDA = \angle ACB \), then \( \triangle ABC \) is a/an:
The ratio of the areas of two similar triangles is equal to the ratio of the------ their corresponding sides.
In \( \triangle PQR \), \( ST \parallel QR \), \( PQ = 12 \) cm, \( PR = 24 \) cm, and \( SP = 4 \) cm, then \( PT = \)
