Question

Please answer these 4...... quickly and must be informative thank you!!!

Answer 1

Ans 1 :- x + 58° = 180° (linear pair)
X = 180 - 58
X = 122°

60° + 58° + y = 180° ( Angle sum property of triangle)
118° + y = 180°
y= 180° - 118°
y = 62°

Ans 3 :- 30 + 42 + angle 1 =180 ( Angle sum property of triangle)
72 + angle 1 = 180
angle 1 = 180 - 72
angle 1 = 108

angle 1 + angle 2 = 180 (Linear pair)
108 + angle 2 = 180
angle 2 = 180 - 108
angle 2 = 72

Ans 4 :- 132 + angle REB = 180 (linear pair)
angle REB = 180 - 132
angle REB = 48

angle REB + 93 + (9x+3) = 180 (Angle sum property of triangle)
48 + 93 + (9x+3) =180
141 + (9x+3) = 180
144 + 9x = 180
9x =180 - 144
9x = 36
x = 36/9
x = 4
9x+3 = 9*4+3
= 36+3
= 39
