If A = L x W. . . Then L = A/W
Answer: D. 0.69
Step-by-step explanation:
You can use SOHCAHTOA to find the right trigonometric identity to use:
Sine = opposite / hypotenuse
Cosine = adjacent / hypotenuse
Tangent = opposite / adjacent
The opposite side of angle A is side BC, which is 20 units long.
The hypotenuse is AB, which is 29 units long.
Opposite / hypotenuse = 20 / 29, which equals 0.689.
The correct choice is D.
Answer:
B
Step-by-step explanation:
x can't repeat
Parallel = same slope
Both will have 4 as slope (m)
Old line: y = 4x - 9
New line y = 4x + b
Plug in the point and solve for b
y = 4x + b
3 = 4(-5) + b
3 = -20 + b
23 = b
New line: y = 4x + 23
