Amplitude is 4. Take the absolute value of value a
Answer:
Angle 1 is 67 and Angle 2 is 46
Step-by-step explanation:
Let the width of the frame = x
Let the cost of a linear foot of the frame = y
Let the inside dimension of the length of the frame = a
Let the inside dimension of the width of the frame = b.
The total length of the frame = 2*a + 4x
The total width of the frame = 2b
The total amount of the frame in feet is (2a + 4x + 2b)*y = Cost

A=h(b+c)
A/h=b+c
b=(A/h)-c
Answer: b=(A/h)-c
