Answer:
x=12, y=60
Step-by-step explanation:
Because the oppsite lines are parallel (you can tell because of the arrows) the opposite lines are the same length and the opposite angles are the same size.
This means y = 60 and x + 3 = 15 so x = 12
Answer:
32 005
Step-by-step explanation:
use this formula
Tn = a +(n-1)d
The sum of interior angles of a triangle is 180°, and a linear pair is supplementary (adds to 180°). The appropriate choice is
... G. w = 105°, because ...
_____
In short, an exterior angle is equal to the sum of the opposite interior angles.
... w = 180 - (180 - (45 + 60)) = 180 -180 +45 +60
... w = 45 +60
