if angle 1 is congruent to angle 4, angle 1 is also congruent to angle 2, how do you get angle 2 is congruent to angle 3

only 2 solutions are positive

also the part with what number should be added to both sides of the equation

should be 2 or 4

so 75 people in the room, 3 more enter so

75 + 3 = 78 so then 2 leave so

75 + 3 = 78 - 2 = 76

then since im not sure what beat up means but im guessing they stayed because it doesnt sya they left so

hope i have a great day!
