The foxglove plant seen in the illustration produces very toxic chemicals that calls serious illness and death in any organism that eats the plant what do the sciences think that the fox low plant evolve such powerful poises

Scientists think that foxgloves have evolved the poisons as an evolutionary adaptation and defense mechanism that provided them with better survival capacities.

As poisons are repellents which help the plants to repel any predator or attacker and enhance their survival. That is why scientists are of the view that old fox glove did not necessarily had this poison many hundred years ago but some how there would be facing harsh circumstances or alot of predators. Due to which, with the passage of time they developed these chemicals which enhanced their life time and survival chances.

Some poisonous chemicals from foxglove are:

if triangle abc is congruent to triangle def, their interior angles are congruent, because congruent parts of congruent triangles are congruent (cpctc).

that means ∠d is congruent to ∠a; ∠d is equal to 8x - 2.

interior angles of all triangles add to equal 180 degrees, so you can set the sum of these interior angle values equal to 180 and solve for x.

180 = (8x - 2) + 22 + 72

180 = 8x - 2 + 22 + 72

180 = 8x + 92

88 = 8x

11 = x

x = 11
