Final answer:
Without additional context about the relationship between angle 5 and angle 27, the value of x cannot be determined from the given equations. Thus, the correct option is C.
Step-by-step explanation:
The student is asked to find the value of x where the measure of angle 5 is given by m∠5=(2x+18)° and the measure of angle 27 is given by m∠27=42°.
To solve for x, we need to establish a relationship between the angles. However, with the information provided, there's no clear relationship indicated between angle 5 and angle 27.
If angles 5 and 27 are supplementary, complementary, or otherwise related, that information is necessary for solving the equation. Without that context, we cannot solve for x.
The complete question is: Find the value of x if m∠5=(2x+18)° and m∠27=42°. Show your work.
