Answer:
d
Step-by-step explanation:
X = <span>parents
x+9 = </span><span>children
x + x + 9 = 25
2x = 25 - 9
2x = 16
x = 16/2
x = 8 </span>parents
8 + 9 = 17 <span>children
Unknowns in this </span><span>problem </span><span>are the number of parents and the number of children.
</span>

Answer:
A triangle's exterior angle is the angle established by one of the triangle's sides and the extension of one of the triangle's adjacent sides.
Step-by-step explanation:
FACTS:
Each vertex of a triangle has two exterior angles.
It's worth noting that the "outside" angles that are "vertical" to the angles inside the triangle aren't called to as triangle exterior angles.
1. The given triangle's angles are 1, 5, and 6.
2. Angle 3 is perpendicular to angle 5 on the inside.
3. The triangle's outside angles are 2 and 4.
The correct answers are A and B.
A triangle's exterior angle is the angle created by one of the triangle's sides and the extension of one of the triangle's adjacent sides.
2x+12=18. 2x+12=-18
Subtract 12 from both sides
2x=6. 2x=-30
Divide both sides by 2
X=3. X=-15
