1. remember what we know about vertical angles and solve for x. (show work)
2. use the figure to answer the questions. (a) what additional information is needed to prove the triangles are congruent by sas postulate? explain.
(b) what additional information is needed to prove the triangles are congruent by the hl theorem? explain. (show work)

Ans 1.

Ans 2.a.

Ans.2.b.

Step-by-step explanation:

Solution:

1.

Vertically opposite angles are equal.

2.a.

proof for Δ BAC ≅ ΔKJL by SAS postulate.

InΔ BAC and Δ KJL

BA ≅  KJ               Given

∠ BAC ≅ ∠ KJL   {measure each angle is 90}

2.b.

proof for Δ BAC ≅ ΔKJL by HL theorem.

InΔ BAC and Δ KJL

BA ≅  KJ               Given

∠ BAC ≅ ∠ KJL   {measure each angle is 90}

hi, i am not sure about this one but i think its d,

hope this !

step-by-step explanation:

the multiplicative inverse of a fraction a/b is b/a. for the multiplicative inverse of a real number, divide 1 by the number. for example, the reciprocal of 5 is one fifth 1/5 or 0.2, and the reciprocal of 0.25 is 1 divided by 0.25, or 4.
