please tell me the correct answer and don't answer if you don't know please please please please please please please​

Answer 1

Answer:

angle 1 is 90 degree

angle 5 is 90 degree

angle 4 is 45 degree

angle 3 is 45 degree

angle 2 is 135 degee

Step-by-step explanation:

60 + 30 + angle 5 = 180 (•:angle sum property)

angle 5 = 180 - ( 60 + 30 )

angle 5 = 90 degree

angle A + angle B = angle 1 (•: exterior angle sum property)

30 + 60 = 90 degree

angle 1 = 90 degree

angle 1 + angle 3 + angle 4 = 180 (•: angle sum property)

90 + 2×angle 3 = 180 (•: given = angle 3 = angle 4)

2 × angle 3 = 180 - 90

2 × angle 3 = 90 degree

angle 3 = 90 / 2

angle 3 = 45 degree

we have given that angle 3 = angle 4

so , angle 4 = 45 degree

angle 1 + angle 4 = angle 2 ( •: exterior angle sum property)

90 + 45 = 135 degree

angle 2 = 135 degee

Answer 2

Answer:

<a = 30 °

<b = 60°

<a+<b+<c = 180°(angle sum property)

30°+60°+<c=180°

<c=180°-90°

<c = 90°=<5

<5+<1 = 180° (linear pair)

90°+<1=180°

<1=180°-90°=90°

<2=180°-<a(30°)

<2=150°

<2=<1+<4(exterior angle property)

150°=90°+<4

<4=150°-90°=60°

<1+<4+<3=180°(angle sum property)

90°+60°+<3=180°

<3=180°-150°=30°
