Answer 1

Answer:

x = 36°

Step-by-step explanation:

There are 180° on a line so 180° - 126° = 54°

54° is one of the angles and so is 90° (because it is a right angle)

Therefore, now we know that x = 180° - (54° + 90°)

54° + 90° = 144°

180° - 144° = 36°

x = 36°

Answer 2

Answer:

x = 36

Step-by-step explanation:

solution:

we have given,

            in the right angled triangle.

             exterior angle = $126^{o}$

we know,

          exterior angle = sum of interior non adjacent angle

   so,   $126^o$ = $x + 90^o$    [∵ one angle of right angled triangle is $90^o$]

     or,  $x = 126^o - 90^o$

     or,  $x = 36^o$

hence, the value of x is $36^o$
