Answer:
x = 12
Step-by-step explanation:
The exterior angle is equal to the sum of the opposite interior angles
3x+19 + 5x = 115
Combine like terms
8x + 19 = 115
Subtract 19 from each side
8x+19 -19 = 115 -19
8x = 96
Divide each side by 8
8x/8 = 96/8
x =12

Step-by-step explanation:
1.
I think the pictures can be matched to the name without knowing the name when a person has already gotten familiar with other works from the particular country or region. Over time, we tend to subconsciously name and or identify things we're seeing for the first time due to having previous knowledge about what something that's closely related to it looks like.
2.
I think yes, it has good community contributions because they have put their respective countries out on the map due to their fantastic artwork. Without these designs, we might not have known the places as much as we do know them now.
Step-by-step explanation:
(1+3x-1)×{1-(3x-1)}
=3x.(1-3x+1)
=3x.3x
=9x^2.
Slope Intercept form is: y=mx+b
Standard Form is: Ax+By=C
Point Slope form is: y-y1=m(x-x1)
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
