Answer:
see explanation
Step-by-step explanation:
Using the tangent ratio in the right triangle
tan A = 
= 
= 
, then
∠ A = 
( ) ≈ 41° ( to the nearest degree )
The sum of the angles in the triangle = 180° , then
∠ B + 41° + 90° = 180°
∠ B + 131° = 180° ( subtract 131° from both sides )
∠ B = 49°
Using Pythagoras' identity in the right triangle
AB² = BC² + AC² = 7² + 8² = 49 + 64 = 113 ( take square root of both sides )
AB = 
≈ 10.6 ( to the nearest tenth )
The correct answer for this question is this one: "
Calculation:
<span>50*.64 + 85*.4= 66</span>
The statement shown above is a topic under Statistics and Probability. As it was said that
<span>The conditional relative frequency table was generated using data that compares the number of voters in the last election and whether or not they worked on election day. Fifty people who voted and 85 people who did not vote were chosen at random and surveyed.
</span>
There exists the same question from other source:
How many people in the survey worked on election day?
32
34
66
69
Hope this helps answer your question and have a nice day ahead.
