Answer:
9 and 3
Step-by-step explanation:
Let the first number be x and second number be y hence their sum
x+y=12 ......(1)
Making x the subject theb x=12-y
Three times be first number is 3x
3x-y=24.......(2)
Adding the two sets of equations then
4x=36
X=36/4=9
The second number will be 12-9=3
So the first number is 9 and second is 3

Answer:
m<A =15, m<B=89, m<C=76
Step-by-step explanation:
A = x
B = 44 + 3x
C = x+61
44 + 3x + x + x + 61 = 180
(you get 5x because you're adding the additional actual value of A to the equation)
now you gotta mush this together
5x + 105 = 180
and now subtract
5x = 75
then divide
x = 15
Great! we found the value of angle A!
now lets plug this in for x in the formulas up top!
B = 44 + 3(15)
B = 44 + 45
B = 89
Yayyyy we're almost done!
C = (15) + 61
C = 76
That's it! that's the value of each angle!
you can check your work by adding the three numbers together to get 180
so lets see
15 + 89 + 76 =
