The conclusion is valid
it is a systematic random sample
and the second one is a line graph (I think)
Answer:
106.44 ft
Step-by-step explanation:
tan = opp/adj
tan61 = opp/59
59*tan61 = opp
opp = 106.438817561014012
Rounded

the shortest side is always opposite the smallest angle.
In triangle ABC the shortest side is AC
In triangle ADC the shortest side is DC
DC<AC since they are in the same triangle.
Since beta is in the first quadrant, the final answer will be positive.
To find cos(beta) so we can use the half angle identity, we can substitute into the Pythagorean identity. Doing so gives us that
So, this means that
