Answer:

60.4°

Step-by-step explanation:

DF is a line, which means ∠DEF = 180°. We also know that ∠DEF = ∠DEB + ∠BEG + ∠GEF. We already know three of these measures, so we can solve for the other:

∠DEF = ∠DEB + ∠BEG + ∠GEF

180 = 110.2 + ∠BEG + 25.6

∠BEG = 44.2°

We know that lines AC and DF are parallel, and since ∠ABE and ∠BEF are alternate interior angles, by definition, ∠ABE = ∠BEF.

∠BEF = ∠BEG + ∠GEF = 44.2 + 25.6 = 69.8°

Then, ∠ABE = ∠BEF = 69.8°.

Again, since AC is a line, ∠ABC = 180°. We also know that ∠ABC = ∠ABE + ∠EBG + ∠GBC. Just like before, we already know three of these angles, so we can solve for the other:

∠ABC = ∠ABE + ∠EBG + ∠GBC

180 = 69.8 + ∠EBG + 34.8

∠EBG = 75.4°

Finally, since EBG is a triangle, we know that its interior angles add up to 180:

∠BEG + ∠EBG + ∠BGE = 180

Plug in the values we know:

44.2 + 75.4 + x = 180

x = 60.4°

Two points are separated on the ground by a distance of 43 km. Can they be placed on a 1 / 25000th map with dimensions 1.32 m on

Wittaler [7]

Answer:

Explanation:

The distance between the two points on the ground = 43km

$\text{Scale}=\frac{1}{25000}$

First, we calculate the distance between the two points in meters.

• 43km = 43,000 m.

Next, determine the distance it will take using the scale.

$\begin{gathered} \frac{1}{25000}=\frac{x}{43000} \\ 25000x=43000 \\ x=\frac{43000}{25000} \\ x=1.72m \end{gathered}$

The distance between the points using the scale is 1.72m.

Next, we see that the dimensions (1.32 m by 0.85 m) are smaller than the length.

As a final check, calculate the length of the diagonal of the map. The diagonal is usually the longest part.

$\text{Diagonal}=\sqrt[]{1.32^2+0.85^2}=1.57m$

Since 1.57m is still less than 1.72m, the two points cannot be placed on the map.
