A researcher proposes that the obligate parasitic weed requires exposure to a signal from the host plant before it can germinate. Using the data as evidence, provide support for the researcher’s claim and give ONE reason the response would be an advantage for the weed plants.

hi,

they have too because they have to be sanitary,

hope this !

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
