5) So for parallelogram ABCD, ∠B ≅ ∠D, and ∠A ≅ ∠C. Further, ∠B and ∠A are supplementary (i.e., their sum is 180°), and ∠D and ∠C are also supplementary.
So, we have that m∠B = m∠D. Therefore,
Now, let's substitute for x back into the expression for either ∠B or ∠D to find it's angle measure.
m∠B =
Now, remember that ∠B or ∠D are supplements of ∠A.
So, m∠B + m∠A = 180°.
That means m∠A = 180° – 72° = 108°.
That seems reasonable, because A appears to be an obtuse angle.
The point-slope equation of the line is
Step-by-step explanation:
The form of the point-slope equation is , where
- m is the lope of the line
- is a point lies on the line
The slope of a line , where
and are two points on the line
∵ The line through (2 , 3) and (7 , 4)
∴ = 2 and = 7
∴ = 3 and = 4
- Substitute these value in the rule of the slope
∵
∴ the slope of the line is
Let us substitute the value of the slope and the coordinates of point in the form of the equation
∵
∵ = 2 and = 3
∵
∴
The point-slope equation of the line is
