Answer:
sin 70° = cos (90° - 70°)
Step-by-step explanation:
You need to use the trigonometric ratios which states that:
sin α = cos (90° - α)
sin 70° = cos (90° - 70°)
sin 70° = cos 20°
85/15 is 5 2/3
so, to find 85% with 15%, you would multiply 12 (also 15%) by 5 2/3.
12*5 2/3=68.
you could also find it using the 1% method:
1% of 15 is .15.
.15*85=68.
Hope this helps!
