Wouldn't all the angles equal 180? We've been trying to learn these but I think so. Subtract both numbers by 180 and it should be the answer. Sorry if it's wrong but I'm not sure. I kinda hope this helps you any
Answer:
Step-by-step explanation:
So first you add them together which gives you infinity and then you divide infinity by (139+285) then keep doing it until you realise this is a scam
The measure represents the standard deviation of the sample means and is used in place of the population standard deviation when the population parameters are unknown is; t-test.
<h3>Which measure is used when the population parameters are unknown?</h3>
A hypothesis test for a population mean when In the case that the population standard deviation, σ, is unknown, carrying out a hypothesis test for the population mean is done in similarly like the population standard deviation is known. A major distinctive property is that unlike the standard normal distribution, the t-test is invoked.

Answer:
20300m^2
Step-by-step explanation:
first try to imagine the shape bisected into a rectangle and a triangle
to find the missing part of the triangle or the bottom side you need to subtract 70m from 140 m
140m-70m=70m this will be the base of your triangle
now you need the side
230m-60m=170
triangle formula base x height/ 2
70m x 170m=a
11900m=a
now the rectangle
base x height=a
60m x140m=a
8400m=a
finally add the two quantities together
8400m+11900m=a
20300m^2=a
