OK. I used my calculator to evaluate sec(85 degrees).
My calculator doesn't have a "sec" button on it.
But I remembered that
sec of an angle = 1 / (cosine of the same angle) .
So I used my calculator to find cos(85), and then I hit the
" 1/x " key, and got 11.474, which I knew to be sec(85).
Answer:
12.75
Step-by-step explanation:
c = π x d
40.035= 3.14 x d
40.035/3.14 = 12.75
Answer:
Any collection of lengths (a, b, c) which do not satisfy the triangle inequalities.
Step-by-step explanation:
Any collection (a, b, c) which do not satisfy the triangle inequalities. The inequalities:
a + b > c
b + c > a
a + c > b
You will need to test all of your options on the three inequalities above. If any one of the three fails, the collection won't work.
Answer:
A
Step-by-step explanation:
note that i = ![\sqrt{-1}](https://tex.z-dn.net/?f=%5Csqrt%7B-1%7D)
given
- 1 + 2i![\sqrt{3}](https://tex.z-dn.net/?f=%5Csqrt%7B3%7D)
= - 1 + ![\sqrt{2^2(-1)3}](https://tex.z-dn.net/?f=%5Csqrt%7B2%5E2%28-1%293%7D)
= - 1 + ![\sqrt{-12}](https://tex.z-dn.net/?f=%5Csqrt%7B-12%7D)
