Answer:
c=
or c=3.46410161514
Step-by-step explanation:
Use Pythagoras theorem: a²=b²+c², where a is the side opposite the right angle, and b and c are the other sides:
a²=b²+c²
4²=2²+c²
16=4+c²
c²=12
c=
or c=3.46410161514
Answer:
53
Step-by-step explanation:
40 + 13 = 53
Answer:
Both X and Y are equal to 15 multiply by the square root of 2.....(i just do not know how to type the symbol on my keyboard)
Step-by-step explanation:
So for X:
X=30 sin 45
=15 multiply by the square root of 2
For Y:
Y=30 cos 45
=15 multiply by the square root of 2
But you could also use theorem of Pythagoras
Answer:
150 degrees
Step-by-step explanation:
90+30=120.
Since angle afc is bisected by line bf, that means that the angles formed equal each other. Since the total angle measurement is 180 degrees, we do 180-120=60. 60/2=30. 120+30=150 degrees.
If a person after 10 steps is at his starting position, then this person takes 5 steps forward and 5 steps backward.
This is a binomial distribution with
- probability to take step forward

- probability to take step backward


Then
