If ` sin C =( 15)/(17) , `then find ` cos C ,`

Find the following : A=(8)/(15) and sin A=(15)/(17) then, Cos A=

In a right angle triangle ABC, right angle is at B ,If tan A=1/sqrt(3) , then find the value of (i) sin A cos C+ cos A sin C " "(ii) cos A cos C -sin A sin C

In Delta ABC right angled at B if tan A = (1 ) /(sqrt 3 ) then find the value of : (i) sin A cos C + cos A sinC (ii) Cos A cos C - sin A sinC

In DeltaABC if A+B= 90^(@) ,then find the value of cos C.

If 5 cos A - 12 sin a = 0 , find the value of (sin A - cos A)/(2 cos A - sin A) .

If A = { 3, 5, 7, 9, 11 }, B = {7, 9, 11, 13}, C = {11, 13, 15} and D = {15, 17} , find A ∩ C ∩ D

In triangle XYZ, angle Y is right angle , XZ =17m and YZ =15 cm then find (1) sin X (ii) cos Z (iii) tan X

If A = { 3, 5, 7, 9, 11 }, B = {7, 9, 11, 13}, C = {11, 13, 15} and D = {15, 17} , find A ∩ (B ∪ C)

In right angle triangle ABC, 8cm ,15 cm and 17 cm are the length of AB,BC and CA respectively , Then find sin A , cos A and tan A .
