Answer:
It would be A.
You can trust me because a right angle is 90 degrees, so you would add the two angles.
Answer:
idk, sorry about that one
Solve for x by simplifying both sides of the equation, then isolating the variable.
x = 10
X² - 10x = 46
10/2 = 5; 5²+ 25 add 25 to both sides
x² - 10x + 25 = 46 + 25
so the number you have to add to complete the square is 25.
