Answer 1

Answer:

<a = 55°

<b = 25°

<c = 55°

<d = 70°

Step-by-step explanation:

For <a

(Sum of angle of triangle)

<a + 100° + 25° = 180°

<a = 180° - 125° = 55°

For <b

(Alternative Interior angle)

<b = 25°

For <c

(Sum of angles on line)

<c + 100° + <b = 180°

<c + 100° + 25° = 180°

<c = 180° - 125° = 55°

For <d

(Sum of angles of triangle)

<d + <c + 55° = 180°

<d + 55° + 55° = 180°

<d = 180° - 110° = 70°
