The first one is A. Number 2 is d. Number 3 is b because 20x20=400 and 21x21=441 and when you add them together you get 841 or 29x29. Number 4 is b because complementary angles are also right angles, they have to add up to 90 degrees. Number 5 is a because every angle is less than 90 degree. Number 6 is 30 because 60+90+x = 180 and when you solve for x you will get 30 degrees.
Point d is at (-1, -2) find the average of the values to get the midpoint

Answer:
The correct answer will be X = 4
Step-by-step explanation:
Using Pythagoras
AB^2 + BC^2 = AC^2
2^2 + (2√3)^2 = AC^2
4 + (4*3) = AC^2
4+12 = AC ^ 2
AC ^2 = 16
AC = √16 = 4
