Why does sin(15) always equal the same number, no matter how big or small you make the triangle.

2 answers:

8 0

This is because sin is opposite over adjacent and this ratio will always be the same in every triangle because a triangle must always add up to 180.

Sin is equal to the same number, no matter how big or small you make the triangle because the sine of the angle is equal to the opposite side divided by the hypotenuse.

Triangle XYZ has vertices X(–1, –3), Y(0, 0), and Z(1, –3). Malik rotated the triangle 90° clockwise about the origin. What is t

OLga [1]

Answer:

Option D.

Step-by-step explanation:

It is given that triangle XYZ has vertices X(–1, –3), Y(0, 0), and Z(1, –3).

Malik rotated the triangle 90° clockwise about the origin. So, rule of rotation is

$(x,y)\to (y,-x)$

Now,

$X(-1,-3)\to X'(-3,-(-1))=X'(-3,1)$

$Y(0,0)\to Y'(0,0)$

$Z(1,-3)\to Z'(-3,-(1))=Z'(-3,-1)$

The image points are X’(–3, 1), Y’(0, 0), Z’(–3, –1).

Therefore, the correct option is D.
