1. Supplementary angles : Two angles are supplementary if their sum is 180°.
For angle 1 and ∠COF to be supplementary,
∠1 + ∠COF =180°
must be satisfied.
We see in the figure that angle 1 and COF form a straight line.
The angle of a straight line is 180°.
∴ 1 is a supplement of ∠COF.
Answer : YES
2. Given : ∠COF =150° ;
AD is perpendicular to BF.
Here, ∠BOC + ∠COF = 180° , since they form a straight line.
∠BOC = 180° - ∠COF = 180° - 150° =30°
∴ ∠BOC = 30°
Answer : D. 30°

Answer: Overpopulation
Explanation:
Overpopulation is a phenomena in which population of a concerned region raises explicitly in large numbers. The two main reasons for overpopulation in India are higher birth rate and lower death rate. India is facing many consequences due to overpopulation like unemployment, poverty, food insecurity, extinction of plant and animal species, loss of ecosystems, deforestation, water and air pollution and others.
Answer:
Aftershocks: Smaller earthquakes that occur after a major earthquake
Body waves: Waves that travel through the interior of Earth; there are two types: primary and secondary waves
Epicenter: Location on the earth's surface directly over the focus of an earthquake
Convection: Process of heat transfer by the circulation or movement of a gas, liquid, or plastic material
Elastic rebound: Immediate return of deformed rock to it's natural shape
Focus: Specific point in the earth where the rock layers along a fault move, producing an earthquake
Liquefaction: Wet soil behaves like a liquid and is no longer able to support buildings during an earthquake
