Every point in the unit circle is identified either by its coordinates or by the angle it forms with the x-axis, .
The trigonometric functions associate with every angle and the correspondant coordinates the two values
This procedure can be done for every angle , so you don't have to work with acute angles only.
Answer:
Right, Isosceles
Step-by-step explanation:
The side lengths of this triangle : 2√8 2√5 2√5
Scalane triangle has all side lengths in different measure but in this triangle we have two side lengths equal
Right triangle has a right angle with 90° and the square measure of hypotenuse is equal to sum of the square length of two side lengths in this triangle since 2√5 + 2√5 = 2√8 we can say that this is a right triangle.
Isosceles triangle are triangles with two side lengths equal to each other
Equilateral triangles are triangles with all side lengths equal to each other but we know one of the side length in this triangle is different
so the answer is Right and Isosceles.
Answer:
its is C because the other ones are obvious wrong. So it has to be C plus i did this test.
