<span>11d=81-16d
Add 16d to both sides
27d=81
Divide 27 on both sides
Final Answer: d = 3</span>
Central angle is 130
Semi circle is BED and BCD
Major arc is CEB
Measure BAC is 130
BEC is 230
Answer:
246
Step-by-step explanation:
next time use a calculator
divide 492 by 2 and you get 246
divide that by 2 and you get 123
and divide that by 3 and you get 41
Form equation
y = mx + c
y = (rise/run).x + c
y = (11-1 / 3--2)x + c
y = 2x + c
11 = 2(3) + c
Find c (y-intercept)
11 - 6 = c
c = 5
Final equation of line
y = 2x + 5
Substitute given possible x-values in to find y-values
y = 2(1) + 5 = 7 (1,7)
y = 2(2) + 5 = 9 (2,9)
Therefore d is correct
The girth because it makes the whole tree bigger and the branches and everything would get bigger too
