Answer 1

what is the equation?

Answer 2

you need to find out what the total of a triangle is.

Answer 3

after, if you know a straight line is 180 subtract 105 from it and you will get the missing angle. then add the angles you know and subtract from the total of the triangle

as melody16 pointed out, add them up

Answer 8

Would X = 38

Answer 9

well, is 67 an internal or external angle?

Answer 10

yes

Answer 11

a internal angle

Answer 12

so,
(180-105) + 67 + x = 180
75 + 67 +x = 180
x = 180 - 142

Answer 13

so, yes

Answer 14

like i said
