Question

Use the figure to find the measures of the numbered angles. ∠1 = ∘ ∠2 = ∘

Answer 1

Step-by-step explanation:

The given angle is 107°;

     Since the lines given are parallel and a transversal cuts them, angle 1 and 107° are corresponding angles.

Corresponding angles are equal;

 So, ∠1  = 107°;

Now, ∠1 and ∠2 are angles on a straight line;

       ∠1 + ∠2  = 180°

         107° + ∠2  = 180°

                    ∠2  = 180°  - 107°  = 73°

Answer 2

Answer: <1= 107      <2=73

Step-by-step explanation: Zigzag method for <1

<1+<2=180

180-<1=<2

180-107=73
