Answer:

The correct answer is that Angle 2 will be 140 and Angle 3 will be 40.

Step-by-step explanation:

In a rhombus, angles opposite from one another are equal. So, since Angle 1 is 140, we know Angle 2 is also 140.

We also know consecutive angles must equal 180. This means the angle in-between 1 and 2 is equal to 40. Since Angle 3 is half of that, we know it to be 20.

Answer:

∠2 = 140° and ∠3 = 20°

Step-by-step explanation:

Only the first two choices make any sense, because the angles in a triangle must sum to 180°.

Only the second choice makes any sense, because ∠2 ≅ ∠1.

Which binomial is a factor of49x^2+84xy+36y^2

Alex17521 [72]

Answer:

(7 x + 6 y)^2

Step-by-step explanation:

Factor the following:

49 x^2 + 84 x y + 36 y^2

The coefficient of x^2 is 49 and the coefficient of y^2 is 36. The product of 49 and 36 is 1764. The factors of 1764 which sum to 84 are 42 and 42. So 49 x^2 + 84 x y + 36 y^2 = 49 x^2 + 42 x y + 42 x y + 36 y^2 = 7 x (7 x + 6 y) + 6 y (7 x + 6 y):

7 x (7 x + 6 y) + 6 y (7 x + 6 y)

Factor 7 x + 6 y from 7 x (7 x + 6 y) + 6 y (7 x + 6 y):

(7 x + 6 y) (7 x + 6 y)

(7 x + 6 y) (7 x + 6 y) = (7 x + 6 y)^2:

Answer: (7 x + 6 y)^2
