Answer:i hope you know the values of trigonometry ratio for 0,30,45,60 and 90 degree. If you dont know than first read the table and try to memorize sin, cos, tan values.

To find :

 \frac{sin30°  + tan45° - cosec60°}{cot45° + cos60° - sec30°}  = ?

Solution :

trigonometric \:  \:  \:  \: ratios </u><u>:</u><u> </u><u>\:  \:  \: . \\  \\ </u><u>sin30</u><u>°</u><u> =  \frac{1}{2} \\  </u><u>tan45</u><u>°</u><u> = 1 \\ </u><u>cosec60</u><u>°</u><u> =  \frac{2}{ \sqrt{3} } \\  cot45</u><u>°</u><u> = 1 \\ </u><u>cos60</u><u>°</u><u> =  \frac{1}{2}  \\ </u><u>sec30</u><u>°</u><u> =  \frac{2}{ \sqrt{3} }

 =  \frac{sin30° + tan45° - cosec60°}{cot45° + cos60° - sec30°} \\  \\  =  \frac{ \frac{1}{2}  + 1 -  \frac{2}{ \sqrt{3} } }{1 +  \frac{1}{2}  -  \frac{2}{ \sqrt{3} } }  \\  \\  = 1

Hope it's helpful ......
