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°
American war strategy with Britain is different compared to a Pacific war set-up. It is inapplicable to do the same in the ocean and with the island around it. However, it gave the American a completely different outlook on waging war in the Pacific. It made them see other war strategies that can adapt to the physical nature of the ocean and islands which are vital to have in an Asia.
The correct option is b. False.
The increase in the greenhouse gas emissions is achieved by a bad production practices, which contributes to global warming.
<span>Some of the human activities that contribute to the increase of greenhouse gas emissions are: burning fossil fuels for electricity, heat, and transportation. If humans don't start thinking how to improve processes for obtained energy, then the planet is going to suffer the consequences, and ultimately, we will also feel them.</span>
Answer:
if all of the food is organic then you would never have rotten food unless you let it rot.
Explanation:
the food will taste much fresher and animalks would want to eat the crops more because they arent made with cemicals.
Answer:
Thermal energy and Tectonic activity
Explanation:
Thermal energy makes the rock in the lithosphere more elastic and Tectonic activity is responsible for some of Earth's most dramatic geologic events such as Earthquakes, Volcanoes, Orogeny (Mountain building), and Deep ocean trenches are all formed by geologic activity in the lithosphere.
