Explanation:
Angles in a heptagon equals 900°
i.e (n-2)×180 where n is substituted for the number of sides.
Find the sum of the remaining angles and subtract it from 900°
120+125+138+82+95+3x+x=900°
560°+4x=900°
4x=900°-560°
4x=340°
Divide both sides by 4
x=85°
while 3x= 255°

Long-term exposure to current ambient PM concentrations may lead to a marked reduction in life expectancy. The reduction in life expectancy is primarily due to increasedcardio-pulmonary and lung cancer mortality.
Increases are likely in lower respiratory symptoms and reduced lung function in children, and chronic obstructive pulmonary disease and reduced lung function in adults. Hope this helped=)
For example, the granite in Figure 2 is made up of the minerals quartz<span>, </span>feldspar<span>, </span>hornblende<span>, and </span>mica<span>. About 20 minerals make up most of the rocks of Earth's crust. These minerals are known as </span>rock-forming minerals<span>.
