Answer:

Step-by-step explanation:
In any triangle, the cosine/cos of an angle is equal to its adjacent side divided by the hypotenuse (longest side) of the triangle. (a/h)
The angle marked 40 degrees has an adjacent side of
and the hypotenuse of the triangle is 60.
Therefore, we have the equation:

Answer:
16
Step-by-step explanation:
Given the equation,
, let's solve for x as follows,
Subtract 200 from both sides


Subtract 15x from both sides


Divide both sides by -5


Answer:
Step-by-step explanation:
2(x - 8) = 24
2x - 16 = 24
Bringing like terms on one side
2x = 24 + 16
2x = 40
x = 40/ 2
x = 20
Answer:
B x=-6
x=2
