19-2x=3x-16
19+16=3x+2x
5x=35
Therefore, x=7.
19-2x=3x-16
19+16=3x+2x
5x=35
Therefore, x=7.
As angle /_ABC is 19-2x,
angle /_ABC is 19-2(7)=5.
Notice the denominator is multiplied by 3, do the same to the numerator: 3*3=9
so 9 is the answer
Answer: it’s the first one the second one and the last one
Step-by-step explanation:
Just took the quiz
A. They are not similar because their corresponding angles are not congruent.
