decide whether enough information is given to prove that the triangle is congruent using the SAS congruence theorem. if so, writ

Paladinen [302]

Answer:

Step-by-step explanation:

Given:

ΔCAD and ΔCBD

∠A ≅∠B (Angle)

AD ≅BD (Side)

From the graph we see that

CD≅CD (Side)

because of reflexive propriety ( a line segment is congruent with itself)

If you put in order those congruencies we have SSA witch does NOT prove congruence.

we not use SAS because the angle between the sides is not congruent

Question Which ordered pairs are solutions to the equation 2x+10y=12? Select all that apply. Select all that apply: (7,−2) (−5,−

AveGali [126]

Answer:

C and D

Step-by-step explanation:

To determine which pairs are solutions, substitute the coordinates into the left side of the equation and if equal to the right side then they are solutions.

(7, - 2)

2(7) + 10(- 2) = 14 - 20 = - 6 ≠ 12 → (7, - 2) is not a solution

(- 5, - 4)

2(- 5) + 10(- 4) = - 10 - 40 = - 50 ≠ 12 → (- 5, - 4) is not a solution

(4, $\frac{2}{5}$ )

2(4) + 10( $\frac{2}{5}$ ) = 8 + 4 = 12 → hence solution

(- 5, $\frac{11}{5}$ )

2(- 5) + 10( $\frac{11}{5}$ ) = - 10 + 22 = 12 → hence solution
