<h2>To construct a 60° angle, we first draw a line of any length. Then using a compass, we use this as a base to construct an equilateral triangle.</h2><h2>To construct the equilateral triangle, we:</h2><h2 /><h2>open the compass to the same dimensions as our original line</h2><h2>place the point of the compass on one end of the line and draw an arc</h2><h2>repeat this at the other end and the arcs should intersect where the tip of the triangle should be</h2><h2>Connect the tip of the triangle to one end of the base, and you will have a 60° angle.</h2><h2 />
The 11 kilometer road will be 1.1 cm long on the map
Step-by-step explanation:
Scale is used on maps to show large locations or roads as small representatives of the larger objects.
The scale factor is usually in proportion to the original length or dimensions.
Given that
1 cm = 10 km
Then, we will divide the number of kilometers by 10 to find the length of road on map
11 km on map =
Hence,
The 11 kilometer road will be 1.1 cm long on the map
