Answer:
Step-by-step explanation:
The values of the cosine function are represented by the axis OX of the goniometric circumference (circumference centered at the origin and of radius 1). Therefore the cosine is zero for the 90º and 270º angles.
Answer:
Step-by-step explanation:
-6.2h-1.2=0.86
-6.2h=2.06
h=-103/310
coordinate of B= (2+3,0) = (5,0)
by pythagoras' theorem,
height of triangle^2 + half length of AB^2 = AC^2
height of triangle^2 = 3^2-1.5^2
height of triangle ^2= 6.75
height of triangle= √6.75
coordinates of C= (1.5,√6.75)
Answer: 8.66666666667
Step-by-step explanation:
Answer:
1.2
Step-by-step explanation:
Because the probability cannot be over 1 (assuming 1 is 100%) you can't have a 120% chance.
