A triangles angles measure up to 180° so before finding x you must find the missing angle.
So lets make an equation:
180=22+23+a
(a is the missing angle)
So add 22+23=45
180=45+a
Subtract 45 from both sides to isolate A
180-45=45-45+a
135=a
135° is your missing angle
So now we have to find X
A straight line measures to 180° so now we subtract 135°(or a) from 180°
180-135=x
x=45
Therefore X is 45°
Answers:
1. the first infographic describes how many jobs were lost in each month of 2019-2020.
2. the third infographic because it includes a visual of a mask, which is related to the subject, to make the infographic look more interesting.
3. the third infographic. it is presented in a simple line graph with clear points to mark the data sets.
4. the first infographic as it mentions the source of the statistics. it also explains the graph using a small text box to help viewers better understand.
[these answers are not the definite correct ones, i'm sure that multiple different answers will be accepted as long as you justify them! also, this isn't the full answer you should give, don't just copy everything word for word. it's simply a rough structure of the answer and you can elaborate more to substantiate your answer :)]
i can give explanations if you need them! hope this helps :D
Answer: A union B = B
The first one should’ve said A intersects B = A because the entirety of A exists in B
Answer:
(c) Multistage sampling
Step-by-step explanation:
Multistage sampling is a technique of sampling in which the population is divided in different stages or groups with the goal of reducing the sample size at each stage.
Here, multistage sampling is being used to obtain the sample of undergraduate students in the United States.
Hence, the correct option is (c), Multistage sampling.
