Question

(Figure is provided below)

Answer 1

Answer:

The measure of ∠z   = 137°

Step-by-step explanation:

Here, angle 1  = 43°

To find : ∠z

Straight line Angle:  The angle which measures exactly 180° and is extended by a point on a straight line is called straight angle.

According to the given figure:

  ∠1 + ∠z  = 180 °  (STRAIGHT LINE ANGLE)

or,   ∠z  = 180 ° - 43° = 137°

Hence, the measure of ∠z   = 137°.
