Answer: m<CBE = 129°
Step-by-step explanation:
we know that,
m<CBE = (14x + 17)°
m<FEH = (19x -23)°
since L║m,
m<CBE = m<FEH
(14x + 17)° = (19x -23)°
through the above equation we formed, we find the value of x :
14x + 17 = 19x -23
19x - 14x = 17 + 23
5x = 40
x = 40/5
x = 8
now we put the value of x in the m<CBE :
m<CBE = (14x + 17)°
m<CBE = ( 14(8) + 17 )°
m<CBE = ( 112 + 17)°
m<CBE = 129° Answer...
hope that helps...
