Answer:
40
Step-by-step explanation:
x = 27.57 in to the nearest hundredth.
The longer diagonal is opposite the obtuse angle.
Also as it is a rhombus all sides = 14 in.
Use the Cosine Rule:
x^2 = 14^2 + 14^2 - 2*14^2 cos 160
x^2 = 760.36
x = sqrt 760.36
x = 27.57 in.
Looking for the area of a regular figure would be taking the longest side and the shortest side and multiply
