Answer 1

Answer:

Answer

1) x+15+45+x+30 = 180 [ Angle sum property of triangle ]

2x + 90 = 180

2x. = 90

x = 90/2

x = 45

2) let the third angle = x

Now,

60+60+x.= 180 ( Angle sum property of triangle)

120 +x = 180

x = 60

3) 40+ 4x. + 3x = 180.(angle sum property of triangle)

40 + 7x. = 180.

7x = 140

x = 20

hope this will help you dear
