N-2, where n is the number of sides.
So for example, an octagon as an n value of 8, so 8-2=6. So an octagon can be divided to 6 nonoverlapping triangles.

Answer:
E. 31.64
Step-by-step explanation:
The mnemonic SOH CAH TOA reminds you of the relation between the legs of a right triangle:
Tan = Opposite/Adjacent
You are given trig values for 36°. That means ...
tan(36°) = 23/x
x = 23/0.727 ≈ 31.64

Answer:
The answer is C
Step-by-step explanation:
Answer:
x-intercept is at (9, 0)
y-intercept is at (0, 6).
Step-by-step explanation:
The x intercept occurs when y = 0:
2x + 3*0 = 18
2x = 18
x = 9,
y-intercept, when x = 0:
2(0) + 3y = 18
y = 6.
