All 3 triangle angles always add up to 180 degrees.
Angle to the left of 140 degrees = 40 degrees
Angle x = 180 -110 -40
Angle x = 30 degrees
Answer:
The required expression is
Step-by-step explanation:
Difference of two minus three = 2-3
Quotient of b divided by the difference of two minus three is
Therefore, the required expression is
