Angles in a triangle add up to 180°


Angles in a straight line add up to 180°


2(x+2)=3(x-3)
2x+4=3x-9

x=13
The number is 13
I'm not sure what the question is here. If an answer is communicative property, go with that. If it is asking for
, the answer is about 84.8230016469.
36 3/4 = 36.75
36 3/8 = 36.375
37 1/2 = 37.5
36 5/8 = 36.625
(36.75 + 36.375 + 37.5 + z) / 4 = 36.625
(110.625 + z) / 4 = 36.625
110.625 + z = 36.625 * 4
110.625 + z = 146.5
z = 146.5 - 110.625
z = 35.875 or 35 7/8 <===
