The correct answer is c. First, look at the argument as it is given in writing then convert it too a proof. So, If p and q then, not r. Next the questions is station that not only does p have to be true so does q if not r is to be true also. So, If (p and q) then, not r. Then to finally convert it into a finalized proof as (p∧q)→¬r.
Answer : we can make only one angle with this because it is necessary to have AB as a base line because the given angle is of <B means we have to make angle at point B . if we take AC as a base line we can not draw angle because we have to make angle at point B so .
. draw a line of AB =7.6
.draw <ABC of 50 degree
.then from point A draw an arc of 5.4 cm at point c
join point A to point C
Because all the angles are congruent (the same), this is an equilateral triangle. All equilateral triangles have congruent angles and congruent sides, so all sides has to be 14.
