Some long-term recommendations to the government department to legislature to solve the crisis of load shedding on tertiary sectors:
Invest in renewable energy sourceImprove the efficiency of EskomHow can the South - African government solve load - shedding ?South Africa is heavily reliant on coal for electricity generation, which is a major contributor to climate change. Investing in renewable energy sources, such as solar and wind power, will help to reduce our reliance on coal and make our energy supply more sustainable.
Eskom is the state-owned utility that generates and distributes electricity in South Africa. Eskom is struggling to meet demand, and load shedding is a result of this. Improving the efficiency of Eskom would help to reduce the need for load shedding.

A bird (B) is spotted flying 5,000 feet from a tree (T). An observer (O) spots the bird (B) at a distance of 13,000 feet. What is the angle of depression from the bird (B) to the observer (O)?
Right triangle OTB is shown. Side TB is labeled 5,000 and side BO is labeled 13,000. The angle B is labeled x degrees.
22.70°
44.62°
67.38°
68.96°
The angle of depression from the bird (B) to the observer (O) is approximately 22.70°.
How to solve for the angle of depressionTo find the angle of depression from the bird (B) to the observer (O), we can use the tangent function, which relates the angle to the lengths of the sides of the right triangle.
In this case, we have side TB (opposite) with a length of 5,000 feet and side BO (adjacent) with a length of 13,000 feet. We want to find the angle B (x degrees).
The tangent of angle B is given by:
tan(B) = Opposite/Adjacent = TB/BO
Substituting the values:
tan(B) = 5,000/13,000
Using a calculator, we can find the value of B by taking the inverse tangent (arctan) of both sides:
B = arctan(5,000/13,000)
The approximate value of B, to two decimal places, is 22.70°.
Therefore, the angle of depression from the bird (B) to the observer (O) is approximately 22.70°.
