Question

Which equation can be formulated from this problem situation? Two angles of a triangle measure 60 and 30 degrees. What is n, the number of degrees in the third angle?

A.(60 + 30) - n = 180
B.(60 + 30) + 180 = n
C.(60 + 30) - 180 = n
D.180 - (60 + 30) = n

Answer 1

It’s C it’s ok if you don’t believe but adding both the angles then subtracting by 180 would be the answer to the third angle with whatever amount comes out from subtracting ......hope this helps >>3
