Answer:
84.3211111111/ 84.32/ 84.3
Step-by-step explanation:
In order to find range, you have to add all the numbers up and then divide by the amount of numbers that you have. So, you'd do 90.89+ 87+ 79+ 89+ 84+ 80+ 85+ 85+ 79= 758.89. Then, since you have nine numbers, you'd divide 758.89 by nine, which equals 84.3211111111, and is rounded to 84.32, or 84.3.
Answer:
A
Step-by-step explanation:
The exterior angle is equal to the sum of the opposite interior angles.
Call the inside angle D
A+ B + D = 180 sum of the angles of a triangle is 180
C+D = 180 since the form a straight line
Solving for D
D = 180-C
Substitute this into the first equation
A+ B + 180-C = 180
Subtract 180 from each side
A+ B + -C =0
Add C to each side
A + B = C
This proves the theorem
