Answer:

x = 36

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

Answer:

x = 36°

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°
