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:
Lower
Explanation:
A pressure surface is an atmospheric surface where everywhere along that surface the pressure is equal. The surface pressure over that area is directly proportional to the air mass
Change in air pressure at a given locality often indicates a change.
Increases in air pressure do not apply exclusively to altitude. At the surface of Earth, small but significant pressure fluctuations are related to the strength of the insolation.

Multiply numerators and then multiply denominators. Or you can change them to decimals and use a calculator.
