Answer:
why do you want me to justify the answer?
Step-by-step explanation:
Answer:
<A = 30
<B = 150
Step-by-step explanation:
- cos<A = AK / AB
- AK = 4
- AB = 8
- Cos<A = 4/8
- Cos<A = 1/2
- A = Cos-1(0.5)
- A = 30 degrees
- Since BC and and AD are parallel, the interior angles of <A and <B sre supplementary.
- <A + <B = 180
- 30 + <B = 180
- <B = 180 - 30
- <B = 150
Total length of the board = 30 inch
Length of,
-- First piece = x
-- Second piece = 4x
-- Third piece = 5x
5x + 4x + x = 30
10x = 30
x = 3
Therefore, the lengths of:
-- First piece = 3 inch
-- Second piece = 4*3 = 12 inch
-- Third piece = 5*3 = 15 inch
Answer: Yes, Raoul is correct because the initial value, also known as the y-intercept of function A is 0 and function B is 3.
Step-by-step explanation: The initial value is when x=0.
