Answer:
The correct option is B.
Step-by-step explanation:
Given information: AB\parallel DCAB∥DC and BC\parallel ADBC∥AD .
Draw a diagonal AC.
In triangle BCA and DAC,
AC\cong ACAC≅AC (Reflexive Property of Equality)
\angle BAC\cong \angle DCA∠BAC≅∠DCA ( Alternate Interior Angles Theorem)
\angle BCA\cong \angle DAC∠BCA≅∠DAC ( Alternate Interior Angles Theorem)
The ASA (Angle-Side-Angle) postulate states that two triangles are congruent if two corresponding angles and the included side of are congruent.
By ASA postulate,
\triangle BCA\cong \triangle DAC△BCA≅△DAC
Therefore option B is correct
x = 1 because -7(3x + 4) must be -49 so 3x + 4 must me 7 so x = 1
Answer:
radical 232
Step-by-step explanation:
14^2+6^2=x^2
196+36= 232
radical 232
423 = 100 + 100 + 100 + 100 + 10 + 10 + 3
hope this helps
It d because one x-value correspond two different y-values
