Answer:
Answer:
9.46 = y
Step-by-step explanation:
=================================================================
You have to use the cosine function equation.
cos(38) =
Multiply 12 on both sides.
12cos(38) = y
Solve.
9.46 = y
How to know which one to use:
Sin, Cos, Tan, Sec, Cosec, and Cot
Sin function is to do opposite number side length over the hypotenuse number side
Cos function is to do adjacent (side length that is next to angle) over the hypotenuse
Tan function is to do Opposite over Adjacent,
These are the inverse of each one
Sec is hypotenuse over opposite (inverse of Sin)
Cosec is hypotenuse over adjacent (Inverse of Cos)
Cot is Adjacent over Opposite (Inverse of Tan)

Answer:
draw a line that intersects the first line at an acute angle using a straightedge
Step-by-step explanation:
perpendicular lines are lines that cross each other (not rays)
The answer is 4 because 14-9=5 and 20/5=4
15. 6 - -3 = 6 + 3 = 9. Answer: 9 degrees C
16. 7 - -7 = 7 + 7 = 14. Answer: 14 degrees F
17. -1 - -5 = -1 + 5 = 4. Answer: 4 degrees C
18. 5 - -2 = 5 + 2 = 7. Answer: 7 degrees C
19. 130 - -110 = 130 + 110 = 240. Answer: 240 degrees C
