Answer:

z = 53

Explanation:

Comment

The three angles of any triangle add up to 180o. There are no exceptions to this rule.

Formula

2z + z - 15 + 36 = 180 Combine like terms on the left.

Solution

3z + 21 = 180 Subtract 21 from both sides

3z + 21 - 21 = 180 - 21 Combine

3z = 159 Divide both sides by 3

z = 53
