Answer:
The measure of ∠A = 58.0°
Step-by-step explanation:
we will use the trigonometry function "tan" to solve the question
∵ BC is the opposite side of ∠A
∵ AC is the adjacent side of ∠A
∵ tan A =
∴ tan A =
∵ BC = 8 units
∵ AC = 5 units
∴ tan A =
→ Use the inverse function of tan to find the measure of angle A
∵ m∠A =
∴ m∠A = 57.99461679°
→ Round it to the nearest tenth
∴ m∠A = 58.0°
∴ The measure of ∠A = 58.0°

Considering the definition of map and scale, an actual distance of 269.59 km represent a scale distance of 5.7 inches .
<h3>Definition of map and scale</h3>A map is a representation of a place, at a size smaller than the real size.
The scale of a cartographic representation is the relationship of similarity between the real dimensions of the geographical space represented and those of its image on the map. That is, the scale is defined as the proportionality relationship that exists between a distance measured on the ground and its corresponding measurement on the map.
One way to represent the scale is by a fraction, which indicates the proportion between the distance on a map and its corresponding distance in reality:
In this case, you know that a scale distance of 3.5 inches on a map represent an actual distance of 175 km.
To know the real distance that represents a scale distance of 5.7 inches, as the scale ratio is the same as in the previous case, it is expressed:
Solving:
×distance in reality= 5.7 inches
distance in reality=
<u><em>distance in reality= 269.59 km</em></u>
In summary, an actual distance of 269.59 km represent a scale distance of 5.7 inches .
