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? |
