Can I please get help I don’t understand this

147, 76 and 56.5

Step-by-step explanation:

11, and 12

Both of these questions require that you find the sum of both angles, and you know this because an angle written down starts with an outside point, a middle point then another outside point. So n, the left side, p the middle, and q, the outside. You add everything in between, the 78 and 68, and you get 147.

13

13 is different because a straight line is equal to 180 degrees, we know this because a full circle is 360 degrees and you split in in half with a straight line going through the center and you get 180 degrees on each side, so with this one you just take 180 - 23.5, and you get 56.5!
