x°=46
Explanation:
There are two methods of solving this question
Method 1:
x°+90°=136° the theorem states that "the sum of two opposite interior is equal to the exterior"
x°=136°-90°
x°=46°
or
Method 2:
136° is on a straight line which is 180°
so, let the other side of the straight line be a.
therefore, 136°+a°=180° theorem {Angle on a straight line}
a°=180°-136°
a°=44°
so, in the triangle is the sum of 180°
a°+90°+x°=180° theorem {Sum of angles in a triangle}
44°+90°+x°=180°
x=180°-134°
x°=46°
