Answer:
From the attached graphic we see that
rhombus side = Sqr Root [(Long Diagonal / 2) ^ 2 + (Short Diagonal / 2) ^ 2]
rhombus side = Sqr Root [(24/2)^2 + (18/2)^2]
rhombus side = Sqr Root [144 + 81]
rhombus side = Sqr Root (225)
rhombus side = 15 feet
Step-by-step explanation:
Answer:
√7 ≈ 2.646
Step-by-step explanation:
The law of cosines is applicable. It tells you ...
c² = a² + b² - 2ab·cos(C) . . . . . where a, b, c are triangle side lengths, and angle C is opposite side c.
Filling in the given information, you have ...
c² = 2² + 3² - 2·2·3·cos(60°) = 4 + 9 - 12·(1/2) = 7
c = √7 ≈ 2.646
The length of the third side is √7, about 2.646 units.
