For this question you will have to find your own set of data for your area, just go to weather.com or a similar site and make a set of temperatures for the next 7 days in your area. The mean can be found by adding all temperatures, then dividing their sum by the number of objects being added.
For example, if my set of temperatures were {75, 90, 83, 77, 91, 88, 80}, I would find the mean with the equation (75 + 90 + 83 + 77 + 91 + 88 + 80)/7, or 83.4
Answer:
m<A = 69°
m<C = 69°
Step-by-step explanation:
From the question given above, the following data were obtained:
AB = AC
m<B = 42°
m<A =?
m<C =?
Since:
AB = AC
Therefore,
m<A = m<C
A + B + C = 180 (sum of angles in a triangle)
C + 42 + C = 180
Collect like terms
C + C = 180 – 42
2C = 138
Divide both side by 2
C = 138 / 2
C = 69°
Finally, we shall determine m<A. This can be obtained as follow:
m<A = m<C
m<C = 69°
Therefore,
m<A = 69°
