Answer:
N-12 = 20
N=32
Step-by-step explanation:
Difference means subtract, is means equals
N-12 = 20
Add 12 to each side
N-12+12 =20+12
N = 32
For the options C, D, and E, (where the 3 sides are given) result in the construction of unique triangles.
<h3>Which conditions will result in the construction of a unique triangle?</h3>
We will have unique triangles only if the length of the 3 sides are completely determined, so we need to know the 3 sides, or two sides and one angle.
With that in mind, for options C, D, and E (in the 3 cases the 3 sides of the triangles are given). Then for these 3 options, we can make a unique triangle.
While for the first two options, where we only know the angles, we can make infinite triangles.

Answer:
i think its 2, but if im wrong im sorry
Answer:
y = 5x - 7
Step-by-step explanation:
slope m = (y₂ - y₁) / (x₂ - x₁)
= (-12 - 3) / (-1 - 2)
= (-12 - 3) / (-1 - 2)
= -15 / -3
m = 5
y-intercept using slope above and anyone point, let's use (-1, -12):
y = mx + b
-12 = 5(-1) + b
-12 = -5 + b
b = -7
Equation of line using m and b from above:
y = mx + b
y = 5x - 7
