Answer:
Step-by-step explanation:
if Pierre moves 1 mile in 18 minutes
1 miles..............................18 minutes
? miles...............................30 minutes
the number of miles=30/18=10/6=1.66 miles
sin = 1.333333
cos = 0.75
-3x^2
negative three x squared
133°
angles on a straight line = 180°
180 - 144 = 36°
angles in a triangle = 180°
36 + 31 = 67
180 - 67 = 113
answer = 113°
x = 10.6
5x - 11 = 42
first +11 so,
5x = 53
then ÷5
