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:
multiply lenght x width x height and multiply by 2 that should get you 392
Step-by-step explanation:
The cost of one pair of shoes is $8.
The cost of one shirt is $12.
<h3>What are the linear equation that represent the question?</h3>
2a + b = 32 equation 1
2a + 3b = 48 equation 2
Where:
- a = cost of 1 shirt
- b = cost of one pair of shoes
<h3>What is the cost of one pair of shoes?</h3>
Subtract equation 1 from equation 2
2b = 16
b = 16/2
b = $8
<h3>What is the cost of one shirt?</h3>
Substitute for b in equation 1
2a + 8 = 32
2a = 32 - 8
2a = 24
a = 24 / 2
a = $12
