Donavan is measuring the angles of a triangle. He measures the first two angles and gets 10 and 120. What should be the measure of the third angle

the third angle should equal 50 degrees.

Step-by-step explanation:

the angles of a triangle always add up to 180 degrees.

10+120=130

180-130=50

therefore, the last angle=50 degrees

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.
