1st, let's calculate the side AB = c in applying the law of cosine:
AC² = BC²+AC² - 2AB.BC. cos87°)
c²= 10.1²+9.8²-2(10.1)(9.8)(cos(87)
c²=102.01 + 96.04 -196.96cos(87)
c² = 187.74 and c = 13.7
Having calculated the 3rd side, now we can apply Heron's formula for the area:
AREA = √p(p-a)(p-b)(p-c), where p is half the perimeter or p=(a+b+c)/2 =16.8
AREA = √16.8(16.8-10.1)(16.8-9.8)(16.8-13.7)
AREA = 49.42 OR 49.4 unit²
(A) Corona, chromosphere, photosphere
<u>Explanation:</u>
- Photosphere - it is the Sun’s deepest layer, and the layer visible to human eyes directly from the Earth. It is also called the solar surface
- Chromosphere - This layer of the Sun is located between 250 miles and 1300 miles above the photosphere. The chromosphere has temperatures around 4000K at the base, and 8000K at the top.
- Transition Region - This layer is very thin with a size of about 60 miles, and it is present between corona and the chromosphere.
- Corona - This layer is the Sun’s outermost layer. It starts at roughly 1300 miles over the photosphere and it has no upper limit. Its temperature is between 500,000 K to 1 million K.
