Answer:

x=42°

Step-by-step explanation:

In any triangle, when all three angles are added together, their sum will always be 180°:

∠1+∠2+∠3=180

Insert any known values:

29+109+x=180

Simplify the addition:

138+x=180

Use inverse operations to find angle three. Subtract 138 from both sides:

138-138+x=180-138\\\\x=42

Therefore, the unknown angle is 42°.

16, because 2•x would also be 2•3 which is 6, and 5•y is rewritten as 5•2 which equals 10. 10+6=16 :)
