It's hard to say. They might be consecutive scores on math tests taken by a student
who was working hard. They could be the high temperatures on three consecutive
days in Chicago. They might be the posted speed limit at three different places on
a highway through a city. They could be the interior angles of a right triangle. It's
hard to say.
90 - 40 = 50 degrees.
180-(90+40) = 180-130 = 50 degrees JustinBeiberCute: That is the right answer. i just thought 50 because there is 90 degrees in 1 angle. If you have 40... there if 50 degrees left. 90 - 40 _________________ 50 Degrees left
ans: 50 degree. its complement is 90-50=40 degree
40 cause 90-50 = 40
50
90 - 40 = 50 degrees.
The three angles are 40, 50 and 90 degrees.
180-(90+40) = 180-130 = 50 degrees JustinBeiberCute: That is the right answer. i just thought 50 because there is 90 degrees in 1 angle. If you have 40... there if 50 degrees left. 90 - 40 _________________ 50 Degrees left
ans: 50 degree. its complement is 90-50=40 degree
40 cause 90-50 = 40
-40 - 90 = -130
In a quadrilateral, three of the angles are obtuse. Which of the following could not be the angle measure of the fourth angle? 60° 90° 40° 20°
140
40
50 degrees (360 degrees in a quadrilateral)
50
-90 (when you add a negative you simply subtract so -40-50 is -90)
