Answer: They're the same angles/measurements.
Step-by-step explanation: Look closely at both the angles. If you measure them, they will be the same because both angles look the same, but ΔADC's side is flipped.

The line
is already written in the
form. This means that
is the slope. If two lines are perpendicular, their slopes are the anti-inverse of each other, i.e. their product is -1.
So, our perpendicular line has a slope of 
Finally, we want a line passing through (1,1) with slope

Answer:
Step-by-step explanation:
There's no "solving" to be done because its an expression, but im assuming the question wants you to factor.

First, factor out a b^2

Factor the trinomial. What two numbers multiply to equal -10 but add to equal -3? They are -5 and +2

Answer:
12-10=2 / (6×5)=30 / 5×2=10 / 12×2=24 / 6+5-2=9
