Step-by-step explanation:
FInd a common demominator which is 20 and multiply both so it turns into 4 19/20
Answer:
0 < x < 3
Step-by-step explanation:
3 < x + 3 < 6 (Subtract 3 from all terms)
0 < x < 3 (The third option is the answer)
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.
