Answer:
Step-by-step explanation:
x=30
m=abe=180
Answer:
x = 3
Step-by-step explanation:

Square both sides of the equation


(x - 3)(x - 5) = 0
x = 3 or 5
Now, you must always check your results because a result may not satisfy the original equation.
If x = 3, then
and 3 - x = 3 - 3 = 0
So 3 satisfies the original.
If x = 5, then
, but 3 - x = 3 - 5 = -2. Therefore, 5 does NOT satisfy the original equation.
That means that x = 3 is the solution to the equation.
A: ∠3 and ∠2
E: Since ∠3 and ∠2 lie on the same line and on a straight line, they must be supplementary as they must add up to 180° to satisfy the condition of a straight line.
