Triangle angle sum theorem

Answer 1

Z will be equal to 16. here’s my work

Answer 2

Answer:

z = 16°

Step-by-step explanation:

The sum of angles in a triangle is 180°

∠1 + ∠2 + ∠3 = 180°

(z + 29°) + 55° + 5z = 180°

Collect like terms;

6z + 84° = 180°

Subtract 84° from both sides;

6z = 96°

Divide both sides by 6;

z = 16°
