Answer:
31
Step-by-step explanation:
(-1-2)^2+(-5-1)^2
(1+4)+(25+1)
5+26
31
Since m<A ≅ m<C, AB = BC.
And...
x+4=3x-8
-2x=-12
x=6
Since AC=x, AC=6.
answer: AC = 6
Let x be the yearly salary of an architect. Then the yearly salary of a lawyer is 2x-20000.
We can build an equation now! x+(2x-20000)=211000, because the yearly salary of an architect plus the yearly salary of a lawyer is 211000.
We combine like terms to get 3x-20000=211000.
We add 20000 to both sides to get 3x=231000.
We divide both sides by 3 to get x=77000, so the average yearly salary of a lawyer is 77000.
Then, the average yearly salary of an architect is 2(77000)-20000=154000-20000=134000, so the average yearly salary of an architect is 134000.
