please
4 and 5th solve please​

Answer 1

4- a.65

b. 115

c. 115

d. 65

5. cab-93

acb _87

cba-72

Answer 2

Answer:

In 4th question.

angle a = 115°. [ corresponding angle]

_____________________

angle b = 180- a [ linear angle]

angle b = 180-115 = 65°

______________________

In the given triangle

angle b + c + 40° = 180° [ interior angle sum property]

65 + 40 +c = 180

c = 180-105

c = 75 °

_______

angle c + d = 180 [ Linear pair]

d = 180-75. = 105 °

__________________

5th question.

In triangle ACD

angle d = 180- ( angle a + angle c)

d = 180-131

angle d = 49°

angle d = angle ABC

Opposite angles of||gm

Angle ABC = 131°
