first, you would find the sum of all the other angles.
85+115+50 = 250
knowing that the circumference of a circle is 360, you can subtract 250 from 360. which leaves you with 110. hopefully this is correct
53+53+53+53+53+53=318
if you add 53 six times you get 318
Answer:
Equation: 
Solve for n: n = 112
Step-by-step explanation:
To first set up the equation, you need to look at the verbal description and translate into numbers and operations:
'three fourths a number' = 
'plus 8' = + 8
'is' =
'20 less' = - 20
'the number' = n
Put the expressions together:
'three fourths a number plus 8': 
'20 less than the number': n - 20
Set them equal to each other and solve: 
Add 20 to both sides: 
Subtract
from both sides: 
Multiply both sides by
: 
Solve for n: n = 112
Answer:
D
Step-by-step explanation:
Given V varies inversely as T, then the equation relating them is
V =
← k is the constant of variation
To find k use the condition, V = 12 when T = 6
k = VT = 12 × 6 = 72
V =
← equation of variation
