If the fraction is 7/8, the top number would be the numerator. So the numerator is 7.
Answer:
0+6=6
Step-by-step explanation:
2x if x=0 would = 2x0=0 and 3y if y=2 3x2=6 so 0+6=6
Yes because by looking at the figure above i could say that the second option is correct
Step-by-step explanation:
sin α - sin β = 2 cos (α + β)/2 sin (α - β)/2
sin 70° - sin 50° = sin 10°
2 cos (70° + 50°)/2 sin (70° - 50°)/2 = sin 10°
2 cos 120°/2 sin 20°/2 = sin 10°
2 cos 60° sin 10° = sin 10°
2 (½) sin 10° = sin 10°
sin 10° = sin 10° → <u>Proved</u>
90 degrees equals a right angle or a complimentary angle.
