While playing a real-time strategy game, Chris created military units for battle: long swordsmen, spearmen, and crossbowmen. Long swordsmen require 30 units of food and 15 units of gold. Spearmen require 40 units of food and 35 units of wood. Crossbowmen require 35 units of wood and 45 units of gold. If Chris used 1575 units of gold, 2100 units of wood, and 2300 units of food to create the units, how many of each type of military unit did he create? Need to find long swordsmen, spearmen, and crossbowmen.

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
