cot (–270°) = 1
cot (–270°) = –1
cot (–270°) = 0
undefined
Answer:
cot(-270) = 0
Step-by-step explanation:
given cot ( -270)
In trigonometry function we will use cot ( -x) = -cotx
so cot (-270) = - cot270
trigonometry table
II quadrant I quadrant ( All positive)
sin θ 90+θ 90 -θ
cosec θ 180-θ 360+θ
third quadrant fourth quadrant
tan θ 180+θ cos θ 270+θ
cot θ 270 - θ sec θ 360-θ
Given
cot (-270) = -cot ( 270)
= - cot ( 180 + 90) (third quadrant above table)
= -cot 90 =0 ( cot θ positive in third quadrant
Final answer:-
cot(-270) =0
The value of cot(−270°) is undefined because it involves a division by zero, as its calculation is based on the cosine and sine values at −270° on the unit circle, which are 0 and 1, respectively.
To find the value of cot (−270°), we need to understand where −270° places us on the unit circle. A full circle is 360°, so starting at the positive x-axis and moving clockwise (since the angle is negative), we move 270° to end up at the positive y-axis. The cotangent function is the ratio of the adjacent side to the opposite side in a right triangle, or the cosine divided by the sine.
At −270° (or 270° in the positive, counter-clockwise direction), the coordinate on the unit circle is (0, 1). The sine of −270° is the y-coordinate (which is 1), and the cosine of −270° is the x-coordinate (which is 0). Therefore, cot (−270°) = cos (−270°) / sin (−270°) = 0/1. Since division by zero is undefined, cot (−270°) is undefined.

Measures of the interior angles will be found as below.
Interior angles of a triangle is the three angles formed inside the triangle by its sides.
Exterior angles of a triangle is the three angles formed by extending the sides
Given that triangle has an exterior angle with a measure of 120°.
Let a, b and c be the interior angles of the given triangle.
The sum of the exterior angle and the corresponding interior angle is 180°.
Let a be the corresponding interior angle.
a + 120 = 180
a = 180 - 120
a = 60°
One of the interior angles is 60°.
Sum of the interior angles of a triangle is 180°.
Then a + b + c = 180
b + c = 120
If the triangle is equilateral, then all the angles will be 60°.
If it is right angle, angles will be 30° and 60°.
Hence the interior angles can be found as above.
