Answer: " y = 30° " .
_____________________________________
<u>Note</u>: The sum total of the measure of all angles lying on a straight
line is 180°.
So; x + y + z = 180 .
Given: x = 2y ;
z = 3y ;
__________________
Find the value of: " y " ;
_______________________
Since: x + y + z = 180 ;
Substitute: "2y" for "x" ;
and: "3y" for "z" ;
_______________________
2y + y + 3y = 180 ;
6y = 180 ;
______________________
Divide EACH SIDE of the equation by "6" ; to isolate "y" on one side of the equation; and to solve for "y" ;
___________________________
6y/ 6 = 180 / 6 ;
y = 30 ;
____________________________
Let us check our work;
____________________________
2y + y + 3y = 180 ;
Substitute our solved value: "30" ; for "y" ; in the equation; to see if the equation holds true:
____________________________
2(30) + 30 + 3(30) =? 180 ?
____________________________
60 + 30 + 90 = ? 180 ?
____________________________
90 + 90 = ? 180 ? Yes!
____________________________
The answer is the last choice in the list. Angle A and angle B are equivalent angles.
Hope this helps! :)
A. because asexual reproduction creates many at the same time and all of them can be very different.
Answer:
Food web
Step-by-step explanation:
Food chain describes how each living organism feed.
Plants are producers because the use photosynthesis to grow and provide nutrients which animals later come to consume, because animals devour plants or animals because they cannot produce their own food like plants. The animals are known as consumers.
Fungi is also a consumer because it absorbs the nutrients available from other living organisms.
Consumers are classified into three types:
1. Carnivores are organisms that feed mainly on animals
2. Herbivores who feed on plants
3. Omnivores who feed on both plants and animals.
A food web describes the relationship between various food chains and how they interact with each other in the eco system.
