If theta and phi are angles in the 1^(st) quadrant such that 1^sttantheta=1/7 and sinphi=1/sqrt10 , then

If theta and phi are angles in first quadrant and tan theta=(1)/(7) and sin phi=(1)/(sqrt(10)) then

If theta and phi are angles in first quadrant and tantheta=1/7 and sinphi=1/sqrt10 then theta+2phi =?

If theta and phi lie in the first quadrant such that sin theta =(8)/(17) "and cos " phi =(12)/(13) find the values of (i) " sin"(theta- phi) " "(ii) " cos " (theta + phi) " " (iii) " tan " (theta - phi)

If theta & phi lies in teh first quadrant such that sin theta=8/17 and cos phi=12/13 then find the value of sin(theta-phi)

If theta and phi are acute angles, sin theta=1/2, cos phi= 1/3 , then the value of (theta + phi) is:

If theta and phi are acute angles satisfying sin theta=1/2, cos phi=1/3 then theta+phi=

If theta and phi are acute angles satisfying sin theta=1/2, cos phi=1/3 then theta+phi=
