Answer:
Those markings represent "absolute value"
It basically means to remove any negative sign in front of a number, and to think of all numbers as positive.

You take 180 subtract 54 and divide it by 2 that gives you the answer.
Answer:
x = 86
y = 67
z = 94
Step-by-step explanation:
The sum of interior angles in a triangle is equal to 180
38 + 56 + x = 180
94 + x = 180 subtract 94 from both sides
x = 86
The sum of two interior angles in a triangle is equal to an exterior angle that is supplementary to the third interior angle so the value of z:
56 + 38 = 94
again the sum of interior angles in a triangle is equal to 180:
19 + z + y = 180 we found z as 94
19 + 94 + y = 180
113 + y = 180 subtract 113 from both sides
y = 67
5+5=10
3+1+1=10
1+1+1+1+1=10
Hope this Helps!
