In circle C shown below, a tangent has been drawn at point A. If m CBA 28 then explain why the measure of DAB must equal 62.
Answers
Answer:
The solution is shown below
Explanation:
From the image attached:
Line BC and line AC are the radii of the circle, therefore BC = AC.
Since BC = AC, the triangle ABC is an isosceles triangle with m∠CBA = m∠CAB = 28°
Also line ED is a tangent to circle C. From the circle theorems, a tangent to a circle is at right angle to the circle radius at point of contact. Since AC is a radii, ∠EAC = 90°
Therefore:
∠DAB + ∠EAC + m∠CAB = 180° (sum of angles on a straight line)
∠DAB = 180° - ∠EAC - m∠CAB
∠DAB = 180 - 90 - 28 = 62
∠DAB = 62°

-heat and rain
- heat and dryness
- always near an ocean
- ice year round
Answers
Answer:
A is to always near an ocean
B is to heat and rain
c is to heat and dryness
d is to ice year round
Explanation:
Im going to use the Koppen climate classification system. But first, some history. The Köppen climate classification is one of the most widely used climate classification systems. It was first published by the German-Russian climatologist Wladimir Köppen (1846–1940) in 1884, with several later modifications by Köppen, notably in 1918 and 1936. So, there are many groups but im going to just do the basics. A is moderate because as you go near water, land attracts heat more than water because of waters specific heat captivity. So the temperature is cooler than the land farther away from the ocean. B is heat and rain because that is typical weather in those areas. C is heat and dryness because there like no rain. Its all ways hot and dry. And finally, d. D is ice year round because its cold and that would make more sense .

Which is the best estimated pressure, represented in units of GPa, of the lower mantle? 110 GPa 220 GPa 305 GPa 360 GPa
Answers
The correct answer is A. 110GPa
Explanation:
Pressure refers to a force applied to a surface or object either by another object or factors such as the atmosphere. This is calculated considering the force applied and the area. Additionally, this factor can be measured using the unit gigapascals (GPa), which is more common in geography and related areas.
In this context, the lower mantle, which is the layer below the upper mantle has a pressure between 24GPa and 130GPa; and this is a high pressure if compared to the pressure in the surface. Thus, the estimated pressure in this zone is 110GPa because this is the only number that is between the range of pressure in this zone, while others show a higher pressure that is not found in this layer.
Answer:110 GPa
