Answer: rhombus
Step-by-step explanation:
By inspection, we can tell that there are no right angles, so we can determine it is not a square or a rectangle.
From the options, it is implied that it is a parallelogram, so to determine if it is a rhombus, we can determine if there is a pair of consecutive congruent sides.
By the distance formula,
![AB=\sqrt{(-1-3)^{2}+(-1-1)^{2}}=\sqrt{16+4}=2\sqrt{5}\\BC=\sqrt{(-1-1)^{2}+(-1-3)^{2}}=\sqrt{4+16}=2\sqrt{5}](https://tex.z-dn.net/?f=AB%3D%5Csqrt%7B%28-1-3%29%5E%7B2%7D%2B%28-1-1%29%5E%7B2%7D%7D%3D%5Csqrt%7B16%2B4%7D%3D2%5Csqrt%7B5%7D%5C%5CBC%3D%5Csqrt%7B%28-1-1%29%5E%7B2%7D%2B%28-1-3%29%5E%7B2%7D%7D%3D%5Csqrt%7B4%2B16%7D%3D2%5Csqrt%7B5%7D)
As AB=BC, there is indeed a pair of consecutive congruent sides, and thus the most specific classification is a <em>rhombus</em>
Answer:
x ≈ 121.2 ft
Step-by-step explanation:
Using the tangent ratio in the right triangle
tan60° =
=
( multiply both sides by 70 )
70 × tan60° = x , then
x ≈ 121.2 ft ( to 1 dec. place )
