Answer:
x = 136°
Step-by-step explanation:
the third angle of the triangle is 180 - (90+46), which is 44. Because a straight line is 180°, x is 180 - 44. x = 136°
look according to the exterior angle of triangle
exterior angle = sum of other two angle (except adjacent angle of that exterior angle)
so x=90°+46°=136°
