The answer is:
(null hypothesis) u=2.7; Ha(alt hypothesis): u<2.7
True.....a polygon will always have the same number of angles and sides. ex: a triangle has 3 sides and 3 angles, a Pentagon has 5 sides and 5 angles, a square has 4 sides and 4 angles...etc.
Answer:
7.9 ft
Step-by-step explanation:
The hypotenuse is the side opposite of the right angle, hence the hypotenuse for this triangle is 11 ft.
Side
is adjacent to the angle given. So we need adjacent and we have hypotenuse. Which trigonometric ratio relates adjacent and hypotenuse? It is COSINE.
<em>Thus, we can write:</em>

<em>Cross multiplying, we can solve for
:</em>

Rounding to nearest tenth, we have
ft.
