Answer:
m<PQR = 80°
Step-by-step explanation:
<u>Points to remember</u>
Sum angles in a linear pair is 180
<u>To find the value of x</u>
It is given that, angle PQR and angle RQS are linear pairs, and
m< PQR =5x+5 and m<RQS =11x-65
m<PQR + m<RQS = 180
5x + 5 + 11x - 65 = 180
16x -60 = 180
16x = 180 + 60
16x = 240
x = 15
<u>To find the value of angle PQR</u>
m<PQR = 5x + 5
= 5*15 + 5
= 75 + 5 = 80
Therefore m<PQR = 80°
Answer:
They're both science
Step-by-step explanation:
The meaning of the constant is the average temperature at the equator statement (A) is correct.
<h3>What is the line of best fit?</h3>
A mathematical notion called the line of the best fit connects points spread throughout a graph. It's a type of linear regression that uses scatter data to figure out the best way to define the dots' relationship.
We have a line of best fit for the data:
y = 90 - z
Here, x is measured in degrees of latitude and y is measured in degrees of Fahrenheit.
When z = 0
y = 90
Which shows the average temperature at the equator.
Thus, the meaning of the constant is the average temperature at the equator statement (A) is correct.
