Las funciones trigonométricas se utilizan fundamentalmente en la solución de triángulos
rectángulos, recordando que todo triángulo rectángulo tiene un ángulo de 90° y sus ángulos
interiores suman 180°. La notación que se acostumbra es la siguiente.

Answer:
(-4,3)
Step-by-step explanation:
go up 4 units, now you're at (4,3)
reflect across the y axis, now youre at (-4,3)
Divide the total $ raised by the cost per tube.
=$3428 ÷ $2 a tube
=1714 tubes can be purchased
She can buy approximately B) 1700 tubes with $3428.
Hope this helps! :)
When the quadrilateral is split into 2 triangles, they are isosceles (as two sides are equal, given in the image) so the base angles are equal. Angles in a triangle sum to 180° so (180-82)/2= 49°, a.k.a the value of angle y.
