Need help on this one too

First let's calculate the measure of our angle.

360 degrees - 296 degrees = 64 degrees.

Now, we can set the sum of our tiny angles equal to the whole angle.

64 degrees = 29 degrees + (x - 24) degrees.

Combine like terms.

64 degrees = 5 degrees + x

Subtract 5 degrees from both sides.

59 = x

c is the correct answer
