Answer:
B = 38°
Step-by-step explanation:
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°
C)-2/3is the answer because when your have 2/3+-2/3 will equal 0 in which justifies the additive inverse
<span>s=1/2at^2
2s = at^2
t^2 = 2s/a
t = + square root (2s/a) and </span>t = - square root (2s/a)
or
+ square root (2sa)
t = ------------------------------
a
and
- square root (2sa)
t = ------------------------------
a
