16.4

Step-by-step explanation:

For the 66° angle, the side with length 15 is the opposite leg.

The hypotenuse is x.

The trig ratio that relates the opposite leg to the hypotenuse is the sine.

sin A = opp/hyp

sin 66° = 15/x

x * sin 66° = 15

x = 15/sin 66°

x = 16.4

6(h+1)/2=a

a=area

step-by-step explanation:

its the same thing as a square or rectangle but after multiplying two sides you need to divide it by two.
