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

Statement I: If sin alpha = 12/13, (0 lt alpha lt pi/2) and cos beta =-3/5,(pi lt beta lt (3pi)/2) , then sin(alpha + beta) = 56/65 Statement II : If theta and phi , are angles in the first quadrant such that tan theta =1/7 and sin phi =1/sqrt(10) , then theta + 2phi = 45^(@) Which of the above statements is correct?

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

Statement I: If sin alpha=(12)/(13),(0

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 alpha and beta are angles in the first quadrant sucn than tan alpha = 1/7 and sin beta = (1)/(sqrt10) , then alpha + 2 beta =

If tantheta=3 and theta lies in third quadrant then sintheta=

If tantheta=3 and theta lies in third quadrant then sintheta=
