Question
Find the value of x, y and z
Hint:
Find the value of x using the sum of angles on a straight line .
Find y and z by using vertically opposite angles.
The correct answer is: x = 28 , y = 125 and z = 55
ANS :- x = 28 , y = 125 and z = 55
Explanation :-
Step 1:- Find x
55° + (5x-15)° = 180°
5x - 15 = 125°
5x = 140°
x° = 28°
∴ x = 28
Step 2:- Find y and z by using vertically opposite angles.
z = 55 (vertically opposite angles are equal)
y = 5x-15 (vertically opposite angles are equal)
Substitute 5x-15 = 125
∴ y = 125

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).
