Answer 1

Answer:

135⁰

Step-by-step explanation:

<d=45⁰

<a+<d=180⁰

a+45⁰=180⁰

a=180⁰-45⁰

<a=13⁰

<b=135⁰

Answer 2

Answer:

Hey

we can take 45° = angle 1 (vertically opposite angle)

angle1 + a = 180° (consecutive angle)

45° + a = 180°

a = 180° - 45°

a = 135°

a = b (vertically opposite angle)

135° = b

b = c (corresponding angle)

135° = c

a = b = c = 135°
