Answer:
Answer B, 123 degrees
Step-by-step explanation:
Angle 3 and angle 6 are alternate interior angles. This means that, by the Alternate Interior Angles Theorem, they are congruent, and therefore equal.
Lets solve the problem with a rule of three, knowing that 118 is the 100%:
100% -------> 118
120% -------> x
x = (120)(118)/100
x = 141.6
therefore the 120% of 118 is 141.6

Endeavor to understand the question, analyze it and interpret it into equation.
Given that Helen's age is multiples of 4. Next year it'll be a multiple of 3. Helen's older brother is now 19.
This means Helen current age is multiple of 4 and next year it will be a multiple of 3. Also, Helen's age is less than 19
The two available numbers that fit this analysis and less than 19 are 8 and 9. 8 is multiple of 4. 8 + 1 = 9 which is multiple of 3
Therefore, Helen is 8 years old now
