From the information given in the question,
the only possible conclusion is:
If angle 1 is measured and angle 7 is measured,
the two measurements will be identical.
If angle 1 and angle 7 are related to a particular shape or drawing,
then additional conclusions may be possible, but we'd need to see
the shape or drawing.
B and D because it doesnt matter how you write the equation you still get the same answer,

Step-by-step explanation:
Given




Required
Number of questions answered
First, we need to get the total correct marks obtained by Roy
This is calculated by multiplying the correct marks by number of correct answers


Subtract this from the total scores obtained; This gives the total incorrect answer obtained by Roy


Open bracket


Divide this by -2 to get the number of incorrect answers


Add this to the number of correct answers to give the total number of question answered



<em>Hence, Roy answered a total of 20 questions</em>
