Question
M ∠ A = (4x + 3)° and m ∠ B = (5x + 6)°
Find the value of x if the angles A and B are
I) Complementary
Hint:
Find the value of x using the given conditions like supplementary (or) complementary
The correct answer is: x = 9°
ANS :- I) x = 9° II) x = 19°
Explanation :-
I) m ∠ A = (4x + 3)°and m ∠ B = (5x + 6)°are complementary
if the angles are complementary then their sum is 90°
m ∠ A + m ∠ B = 90°
(4x + 3)° + (5x + 6)° = 90°
9x + 9 = 90
9x = 81
∴ x = 9

A poster has an area of 432 square inches. The length , in inches, of the poster is 6 inches longer than the width of the poster. Which of the following equations can be solved to determine the length, in inches, of the poster?
Note:
The question can be further extended and ask us to find the length, breadth, or the perimeter of the poster. In that case, first we would solve the above equation to find the length of the poster and then use it to find the breadth. Finally we can find the perimeter easily by using the formula: perimeter 
(length + breadth).
