Onece a person had gone for a horse racing area. instead of counting the number of humans an horses, he counted 74 heads and 196 legs. how many humans and horses were there? a. 37 humans and 98 horses b. 24 horses and 50 humans c. 31 horses and 74 humans d. 24 humans and 50 horses

humans: x

horses: y

Heads: 1x + 1y =  74     ⇒   -2(1x + 1y =  74)    ⇒    -2x -2y = -148

Legs:   2x + 4y = 196   ⇒     1(2x + 4y = 196)   ⇒   2x + 4y = 196

                                                                                        2y = 48

                                                                                           y = 24

Heads: 1x + 1y =  74   ⇒   x + (24) = 74   ⇒   x = 50

humans = 50, horses = 24

trapezoid

step-by-step explanation:

first i plotted all my points on a grid graph

i made sure all of them were in the correct quadrant

then i saw it was a trapezoid or a quadrilateral

all the angles opposite to the angle 150 would be 150 and all the angles that are next to 150 are 30 because they equal 180 it you add it up.
