Answer» cosx=3/5; sinx^2=(5)^2-(3)^2=25-9=16; sinx=4/5; sinx-cosx/2 tanx= 4/5 - 3/5/2 (4/5)= =4-3/5 /2(4/3)=-1/5/8/3= 1/5 × 3/8= 8x15/40=120/40= 120/40=12/4=3 cosx=3/5; sinx=4/5; tanx=4/3; (4/5)-(3/5)/2(4/3) = (4-3/5) x 3/8=(1/5)×(3/8)= 8+15/40=23/40 1/30 is the correct answer for this question 1/30 is correct answer |
