In a triangle, one angle is 60 degrees and another is 20 degrees. The remaining angle must be
A. right.
B. acute.
C. obtuse.
D. complementary.

C. Obtuse

Step-by-step explanation:

Triangles angles add up to 180 degrees

60 degrees + 20 degrees = 80 degrees

180 - 80 = 100 degrees

Obtuse angles have angles greater then 90 degrees.

the number of possible outcomes that do not show a 1 on the first spinner and show the number 4 on the second spinner is 2.

3                   4 = not 1, and 4

only 2 outcomes have passed the given condition.
