Find The Missing Angles In The Diagrams Below class=

Sagot :

A. X=51, 2x=102
B. A= 142, c=38, t =38

Answer:

a. 27° + (2x° + x°) = 180° (linear pair)

27° + 3x° = 180°

3x° = 180°-27°

x° = 153°/3

x° = 51°

2x° = 2×51 = 102°

b. a° = 142° (vertically opposite)

c° + a° = 180° (linear pair)

c° = 180° - 142°

c° = 38°

i° = c° = 38° (vertically opposite)
