Answer:
5
Step-by-step explanation:
Each triangle is a myriad of both |, ||, and |||.
Because BE = || and FE = ||| then BF = |
CD = 10 but thats equal to 2 | meaning that 1 | is 5.
Given the equation x would have to be 1 in order for x to be zero
During the precolonial period, the three (3) sequential economies that existed in southern Africa are:
- Hunter-gathering
- Hunter-herding
- Mixed farming
<h3>What is an economy?</h3>
An economy can be defined as a function of how the various means of production, money, and scarce resources (raw materials) are carefully allocated and used to facilitate the demand and supply of goods and services in a country, so as to meet the unending needs or requirements of consumers.
<h3>The three main economies that existed in southern Africa.</h3>
During the precolonial period, the three (3) main economies that existed in southern Africa in an ascending order include the following:
- <u>Hunter-gathering:</u> it was practiced by the precolonial San and it involved hunting for wild animals.
- <u>Hunter-herding:</u> it was practiced by the precolonial Khoekhoe and it involved both hunting for wild animals and pastoralism such as herding of goats, sheep, etc.
- Mixed farming: it was practiced by the Bantu speaking communities and it involved mining, hunting, crop cultivation (agriculture), trade and pastoralism.

Answer:
When a shape is transformed by rigid transformation, the sides lengths and angles remain unchanged.
Rigid transformation justifies the SAS congruence theorem by keeping the side lengths and angle, after transformation.
Assume two sides of a triangle are:
And the angle between the two sides is:
When the triangle is transformed by a rigid transformation (such as translation, rotation or reflection), the corresponding side lengths and angle would be:
Notice that the sides and angles do not change.
Hence, rigid transformation justifies the SAS congruence theorem by keeping the side lengths and angle, after transformation.
