Answer:
100°
Step-by-step explanation:
Total angle in a triangle is 180
∠C = 180 - 20 - 60
= 180 - 80
= 100
Answer:
bro division and fraction are technically same
Step-by-step explanation:
The heat of the sun penetrates the atmosphere and warms the Earth's surface. The warmed rEarth Radiates and this heat back into the atmosphere.The gases the surround the atmosphere such as carbon dioxide , methane , nitrous oxide and water vapour absorb some of the radiated heat and send it back to the Earth . This<em> trapping of heat from the Sun by excess carbon dioxide and other gases present in the atmosphere</em> is known as the <u>greenhouse effect</u>. The gases involved in the phenomenon are called <u>greenhouse gases.</u>

Line YZ is the midsegment of triangle QRS because it connects the midpoints of lines QR and RS. We would solve for x by appying the midsegment theorem which states that the midsegment is half the length of the third side or base. This means that
YZ = 1/2(QS)
x + 2 = 1/2 * (3x - 8)
2(x + 2) = 3x - 8
By opening the parenthesis, we have
2x + 4 = 3x - 8
Collecting like terms, we have
3x - 2x = 4 + 8
x = 12
Option C is correct
