Answer:
A counterexample is sufficient, as long as it is well built and complete.
Step-by-step explanation:
A counterexample is a statement used to show that a previously spoken statement is false.
The counterexample must be direct, clear, simple, well constructed and concise to be effective. If the counterexample has all of these characteristics, only one counterexample is sufficient to show that a conditional statement is flawed.
As an example of this, we can use a square as a counterexample of a statement that states that every rectangle has 4 equal sides.
Answer:
B. 95 degrees
Step-by-step explanation:
first workout the vertically opposite angles;
subtract 121 from 180 to get the other pair of vertically opposite angles.
= 59
do the same for 144 to get = 36
59 and 36 make the interior angles of the triangle. find the third one by adding the two to get 95, then subtracting from 180 to get 85.
since angles on a straight line add up to 180 degrees , subtract 85 from 180 to get 95 as your answer.
hope you understand it welll
