Find the measure of the third angle of a triangle given the measure of two angles are 86º and xº.

a) (86-x)
b) (90-x)
c) (94-x)
d) (180-x)

The total degrees in a triangle is 180. if you add the angles up, it should equal. if we say that the angle of the third angle is y, our equation looks like this
y+x+86=180
if we solve for y, we get
y=180-86-x, which you can solve for for your answer

The correct answer would be A, 86-x

the sum of a triangle will always be 180 the grease.

Step 1: 6x-10=1; step 2: 6x=11

Thats where they was ported and the fields that noone really knew much about needed tended, so they put slaves out there do free work and huge profits and so on the north decided to hold its own and was more different way of survival did not have same climate conditions to afford protecting slaves from winter so expenses be diff from south
