How many angles are in a triangle?
3
300
What is y?
88 degrees!
300
What is the measurement of angle x?
55 + x = 90 (it's a right triangle), so x = 35 degrees
400
Can a triangle have these angle measures?
30, 60, 90.
yes = 180
400
How many degrees do the angles in a quadrilateral add to
360
400
What is x?
42 degrees
400
What are the measurements of angles x and y?
x + 150 = 180, so x = 30 degrees
x and y are vertical angles, so y = 30 degrees
