Answer:
The sum of the angles within a triangle is 180 degree.
Step-by-step explanation:
We are asked to determine why is it impossible for a triangle to contain a 180° angle.
We know that angle sum property of triangle states that sum of all three angles of triangle must be equal to 180°.
We also know that measure of angle on a straight line is 180 degrees. So, if an angle measure to 180 degrees, then it will be a line not a triangle.
Therefore, it is impossible for a triangle to contain a 180° angle.

Answer:
The actual distance between the two places to the nearest tenth of a kilometer is 63.3 km
Step-by-step explanation:
Here, we want to get the actual distance between two places on a map, given the scale used to draw the map and the distance of both places on the map, in terms of the scale.
The scale used here is 1cm to 11.5km
Since 1cm = 11.5km
then 5.5cm = x km
Thus ; x = 5.5 * 11.5
x = 63.25 km
Our answer in wanted to the nearest tenth of a kilometer so the answer is 63.3 km
