Step-by-step explanation:

The angles inside a triangle will always add up to 180°

180 - 91 = 89°

X = 89

A triangle always equals 180°. Because two out of three angles are given, the two known angles (42° and 49°) can be added together which is 91°. The 91° can be subtracted from 180° to find the unknown angle x.
