Answer:

Scalene triangle: A triangle with no congruent sides. Isosceles triangle: A triangle with at least two congruent sides. Equilateral triangle: A triangle with three congruent sides. (For the three types of triangles based on the measure of their angles, see the article, “Identifying Triangles by Their Angles.”)

2x+3y=5,x+y=1 using graphical method in simultaneous equation​
kifflom [539]

Answer:

(-2,3)

Step-by-step explanation:

I used Desmos to input these 2 equations and then locate the point(s) at which they intersect.  Since these are both linear, there will be either 1 solution or none at all, but in this case, there is one solution, and it is at the point (-2,3) which is where the 2 graphs intersect.

Find the exact value of cot 330° in simplest form with a rational denominator.
Hoochie [10]

Answer:

\cot 330^{\circ} = -\sqrt{3}

Step-by-step explanation:

The cotangent function can be rewritten by trigonometric relations, that is:

\cot 330^{\circ} = \frac{1}{\tan 330^{\circ}} = \frac{\cos 330^{\circ}}{\sin 330^{\circ}} (1)

By taking approach the periodicity properties of the cosine and sine function (both functions have a period of 360°), we use the following equivalencies:

\sin 330^{\circ} = \sin (-30^{\circ}) = -\sin 30^{\circ} (2)

\cos 330^{\circ} = \cos (-30^{\circ}) = \cos 30^{\circ} (3)

By (2) and (3) in (1), we have following expression:

\cot 330^{\circ} = -\frac{\cos 30^{\circ}}{\sin 30^{\circ}}

If we know that \sin 30^{\circ} = \frac{1}{2} and \cos 30^{\circ} = \frac{\sqrt{3}}{2}, then the result of the trigonometric expression is:

\cot 330^{\circ} = -\frac{\frac{\sqrt{3}}{2} }{\frac{1}{2} }

\cot 330^{\circ} = -\sqrt{3}
