4.702, so your answer is 4.70. I got this using S-A-S, using the 2 sides and an angle you get 4.702. Can you please answer my question right under this please?
Two unlabelled angles are = 54o
x / sin72 = 4 / sin 54 x = third side = 4.70228 in
Now you can use Heron's Rule to find the area.....are you familiar with it?
Or pythag theorem to find height 4^2 - ( 4.70228/2 )^2 = h^2 h= 3.23606
area = 2 x 1/2 b h = b h = 2.35114 X 3.23606 = ~~7.61 in2 (edited)
