Answer:
La suma de los ángulos interiores de un hexágono regular es 720°
Step-by-step explanation:
Asumamos que el hexágono presentado en el enunciado sea regular, el cual es formado por seis triángulos equiláteros, Un ángulo interno del hexágono está formado dos ángulos laterales y vecinos de dos triángulos equiláteros, es decir, dos veces 60°, o sea, 120°. Si el hexágono regular tiene seis ángulos internos de igual medida, entonces la suma de los ángulos interiores es 720°.

keeping in mind that perpendicular lines have negative reciprocal slopes, and that parallel lines have equal slopes, well, those two slopes above aren't either, so since they're neither, and they're different, that means that lines A and B intersect.
7 Oxen= $280
2,150 Ibs of food= $430
15 clothes= $150
430+280+150=860
Tax- 860 x 1.09= $937.4
