Answer:
x = 27.57 in to the nearest hundredth.
Step-by-step explanation:
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.
The angle is called an hypotenuse and to find it just use the Pythagorean Theorem which states a squared+b squared= c squared, does this answer your question or do you need more help?
8:15 or 8 to 15 would be the ratio because you compare 8 quarters to 15 coins.
