The table below shows the number of tickets sold, t, at a high school basketball game, and the amount of money collected, m.

What is m CDJ? <br>please help me I'm super confused.

Citrus2011 [14]

Answer:

34 degrees.

Step-by-step explanation:

Assuming AK is a straight line and being shown angle JDK is right and 90 degrees it can be stated that 4x + (3x-8) = 90 degrees.

Drop the parentheses and get 7x - 8 = 90.

Add 8 to both sides 7x = 98.

Divide both sides by 7, x = 14.

Plug that x value into (3x-8), [3(14)-8] = 34 degrees.
