To solve you move the variables to the side and divide both sides by the factor number that doesnt have the variables your answer would be b=23/2 as a decimal is 11.5
Its the first one 6(7+12) i took the test and got the answer wrong but then i found out it was this so i hope i helped you ;-;
Answer:
its option B
Step-by-step explanation:
Answer:
Angle-Angle-Side (AAS)
Step-by-step explanation:
Given triangles; ΔABD and ΔCBD
<A = <C = (right angle property)
AB ║ DC (given)
Then,
DA ║ CB
<B ≅ <D (congruent property)
DB ≅ BD (similarity property)
<D + <B = <B + <D (complementary angles, and property of triangles)
Therefore by Angle-Angle-Side (AAS),
∆ABD ≅ ∆CBD
