Answer: 17.5 is located between them.
Step-by-step explanation:
To find out which number is located between the numbers, find their mean average which sum of the numbers divide by the number of values.
15 + 20 = 35
35 / 2 = 17.5
Answer:
m∠PQR = 133
Step-by-step explanation:
∠PQR and ∠RQS are supplementary angles, meaning they have a sum of 180°.
3x - 5 + x + 1 = 180
4x - 4 = 180
4x = 184
x = 46
Now we simply substitute 46 in for x:
3(46) - 5 = 133
The x coordinate is halfway between 2 and 10 = 2 + (10-2)/2 = 2+4 = 6
so midpoint is C (6,3)
