So, yes. A triangle can be formed by the given angles.
Answer:
=2x2y−4x
Step-by-step explanation:
Answer:
85 degrees
Step-by-step explanation:
The angles in a quadrilateral add to 360 degrees, so x+109+96+70=360.
This means that x=360-109-96-70=85 degrees
<u>Corrected Question</u>
Points X and Y are endpoints of a diameter of Circle W. Point Z is another point on the circle. Find the probability that 
XZY is a right angle.
Answer:
Probability=1
Step-by-step explanation:
<u>Theorem</u>
- If an Inscribed angle intercepts a semicircle, the angle is a right angle.
Given that X and Y are endpoints of a diameter of Circle W and point Z is on the circle's circumference.
I have prepared a diagram which is attached.
Then, XZY is an angle which intercepts a semicircle.
By the theorem above, XZY is a right angle.
Therefore, the probability that XZY is a right angle =1
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.
