PLEASE HELP!! A. Beef uses significantly more land than plants to produce 100 grams of protein

B. Meat production is more efficient than farming protein from fish and prawns

C. Lamb and mutton produce more protein per square meters than pig meat and poultry

D. Nuts and grains produce less protein per square meter than milk and cheese

D

Explanation:

I just know it is d XD

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
