You are given values for the adjacent side of <x and the hypotenuse of a right triangle. This defines the Cosine of an angle
Equation
Cos(x) = a/c the way you have labeled it.
Givens
a = 9
c = 18
Solution
Cos(x) = a / c
Cos(x) = 9 / 18
cos(x) = 1/2
x = cos-1(1/2)
x = 60 degrees
Answer
x = 60
Answer:
6 blocks each measuring One-third times 1 times 1
Step-by-step explanation:
Answer:
A = 37
Step-by-step explanation:
l = √(6² + 1²)
= √(36 + 1)
= √37
A = l²
= (√37)²
= √37×√37
= 37
Answer:
60mph
Step-by-step explanation:
Speed is the rate of change in distance. Mathematically,
Speed = Distance/Time
Difference in distance between A and B = 285-105miles = 180miles
Total time taken between 2pm and 5pm is 3hours
Speed = 180miles/3hours
Speed = 60miles/hour
Therefore the train speed between the checkpoints is 60miles/hour
