Answer:
1. x = -7
2. y = -1
Step-by-step explanation:
1.
-3x - 5 = 16 add 5 to both sides
-3x = 21 divide -3 to both sides
x = -7
2.
-4(y-2) = 12 distribute -4
-4y + 8 = 12 subtract 8 from both sides
-4y = 4 divide -4 to both sides
y = -1

1. x = 9
2. y = -3
The answer is 110 degrees
3x + 15 - 9 = 2(x +2)
3x + 6 = 2(x +2)
3x + 6 = 2x + 4
3x + 6 - 2x = 2x - 2x + 4
x + 6 = 4
x + 6 -6 = 4 - 6
x = -2
Hi there!
For a 3,4,5 triangle the smallest angle measure would be 45 degrees.
Hope this helps !
