- if sin (x+30°)=1/2 find x
- in triangle ABC is a right triangle right angle B and sin c is equal to 12 by 25 find the value of sin A cos c minus cos A sin c
-
cot2 30-2cos2 60-3/4sec2 45-4sec2 30
- if sin theta = root3/2, find the value of all t- ratios
- if altitude of sun is 60 degrees then height of vertical tower that will cast shadow of lenght 20m

Please sir solve this
- prove that cosec-cot A) ^2 = 1-Cos A/ 1+ cos A
-
sinA-cosA-1/sinA+cosA-1=1/secA-tanA
- A ladder 15 m long just reach the top of a vertical wall. If the ladder makes an angle 60° with the wall , find the height of wall
