Question

Find the missing values

hint Hint:

Find the value of x and z by using the sum of angles of the triangle is 180°. Then find y by using the sum of angles on a straight line is 180°.

The correct answer is: x = 62 ; y = 59 ;z = 59

ANS :- x = 62 ; y = 59 ;z = 59
Explanation :-
Step 1:- Find x
28°+ 90°+ x°=180°(sum of angles in a triangle)
x°+ 118° = 180°
x° = 180 - 118° x° = 62°
∴ x = 62
Step 2:- Find Z
31°+ 90°+ z°=180°(sum of angles in a triangle)
z°+ 121° = 180°
z° = 180 - 121° z° = 59°
∴ z = 59
Step 3:- Find y
x°+ y°+ z° = 180° (sum of angles on a straight line)
Substitute values of x and z
y° + (62+59)° = 180°
y° = 180 - 121° y° = 59°
∴ y = 59
