Answer:
5.5:1
Step-by-step explanation:
<span>first you set up a proportion 18 over ? = 60 over 100 then cross multiply. 18*100=1800 then divide that by 60 and you get 30 :)</span>
Is this a riddle?? Or are you really doing this :-(
There exists a trigonometric identity which states that,
sin (A - B) = sin A cos B - cos A sin B
This is very similar to the given expression with A equal to 57° and B equal to 13°. The simplified form of the angle is,
sin (57° - 13°) = sin 44°
(7 cm)*(10 cm) = 70 cm^2
The area is the product of length and width.
