That would be false

It is mostly used in non-right triangle trigonometry since it is consistent instead of using right triangle rules

Answer 5

So, the answer to the question that asks "suppose a triangle has sides 1,1 and 1. Which of the following must be true?" is "the triangle in question is not a right triangle?

Answer 6

The law of cosines can be written as
\(c^2 = a^2 + b^2 − 2ab cos(C)\)

or

\(cos(C) = \large \frac{a^2 + b^2 − c^2}{2ab}\)

So you can have 2 sides and 1 angle, or all 3 sides

Answer 7

So, does that mean the answer is c?

Answer 8

No
I said 2 sides and 1 angle, not 2 angles and 1 side
