Question

Look at the fence above what is the measure of angle a 140° to 55° a 135° b 145° c 90° d 45°

Answer 1

The measure of angle a can be determined by subtracting the measure of angle b from the measure of angle c:

Angle a = Angle c - Angle b

Given that Angle c = 140° and Angle b = 55°, we can substitute these values into the equation:

Angle a = 140° - 55°

Simplifying, we get:

Angle a = 85°

Therefore, the measure of angle a is 85°.
