Angles A = 60, B = 2x, C = 3x and D = 25 are 4 angles on a straight, what 3 points is the value of angle B?*

iragen [17]

Answer:

B = 38°

A straight angle is 180°. If your four angles total a straight angle, then ...

60 +2x +3x +25 = 180

95 = 5x . . . . . . subtract 85

x = 19 . . . . . . divide by 5

2x = 38 . . . . . angle B is 38°
