Supplementary angles are two angles whose measures add up to 180° . The two angles of a linear pair , like ∠1 and ∠2 in the figure below, are always supplementary. But, two angles need not be adjacent to be supplementary. In the next figure, ∠3 and ∠4 are supplementary, because their measures add to 180° .
<h3>According to the question;</h3>
- ∠1 ≅ ∠2, which means that both angles are congruent or same.
<h3 /><h3>∠1 + ∠2=180°</h3><h3>∠1=180/2</h3><h3>∠1=90°</h3><h3>∠1 ≅ ∠2</h3><h3>90°=90°</h3>
- <em>Hence, values of ∠1 &∠2 are 90° respectively.</em>

Given
differentiable at
Start by representing y as ;
Solving (I):
Substitute 0 for x in
<em>I is not true</em>
Solving (II):
Substitute 3 for x in
<em>II is true</em>
Solving (III):
First , we have to differentiate
Then, substitute 3 for x in
<em>III is true</em>
As OB is the perpendicular bisector of AD. So AO = OD
Hence
2x + 5 = 3x – 5
3x – 2x = 5 + 5
