Answer:
e. a useful illusion used to map the stars and other objects in the sky
Explanation:
A celestial sphere is a graphical representation whose purpose is to describe the different locations of objects in the sky. A Celestial Sphere depiction contains Earth's rotation axis, North Celestial Pole, South Celestial Pole and Celestial Equator.
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°
C.) Ukraine is the largest among them.
Hope this helps!
The earths surface is heated by the Sun's rays which are directed at the equator 0° latitude. If there were sea currents the closer you got to the equator the hotter it will get and the further away you go from the equator the colder it will get. Thus ocean currents distribute the heat at the equator around the earths oceans to even out the difference in the heat zones, so that the equator is not a desert and the rest of the earth is an ice age.
If X is another angle, keep in mind that when the figure is a triangle the sum of the angles is 180º (angle1+angle2+angle3=180º) ALWAYS!!
