8 0

Answer:

Electricity is a secondary energy source that is produced when energy sources such as coal, natural gas, nuclear, and renewable energy are converted into electric power.

Most electricity is generated with steam turbines using fossil fuels, nuclear, biomass, geothermal, and solar thermal energy. Other major electricity generation technologies include gas turbines, hydro turbines, wind turbines, and solar photovoltaics.

Electricity generation is the process of generating electric power from sources of primary energy.The rotary electrical generator is very efficient by comparison.The conversion efficiency of a large machine can be as high as 98% or 99%.

Given: EF is a diameter of the circle Find m∠EGF. A) 45° B) 60° C) 90° D) 100°
Law Incorporation [45]

Answer:

∠EGF = 90°

Explanation:

Question is incomplete as the attachment is missing.

To solve this I'll make an assumption that ∠EGF is an angle inscribed in the circle.

Given that

Line EF is a diameter;

Then the arc formed by EF is 180° (semi circle).

The inscribed angle theorem states that an angle θ inscribed in a circle is half of the central angle 2θ that subtends the same arc on the circle.

So, the inscribed angle

Arc EF = 2 * ∠EGF

Make ∠EGF the subject of formula

∠EGF = ½ EF

∠EGF = ½ * 180°

∠EGF = 90°
