Question

X =

a) 43
b) 58
c) 71

Answer 1

x=58

Explanation:

Answer 2

`28 \textdegree = (1)/(2) ( 114 \textdegree - \angle x)`


`28 \textdegree = 57 \textdegree - (1)/(2) \angle x`


`(1)/(2) \angle x = 57 \textdegree - 28 \textdegree`


`(1)/(2) \angle x = 29 \textdegree`


`\angle x = 29 \textdegree * 2`


`\angle x = 58 \textdegree`
