Given that the angle measure 20 and the side opposite to that angle measures 10 cm, suppose this is the height of the triangle, the hypotenuse Such that sin theta=opposite/hypotenuse opposite=a=10 cm sin 20=10/h multiplying both sides by h we get hsin20=10 hence; h=10/sin20 h=29.24 cm h=29.2 cm
You need to multiply 188 by 25%. But first convert 25% to a decimal 0.25. 188*0.25 is 47 Now we subtract 188 - 47 Which is 141 $141 is the sales price.
