Question

Find the value of z. 76° Z 112° 78° please somebody help can give 24 points :D​

Answer 1

`z = 94\°`

Explanation:

We know that the measures of the interior angles of a quadrilateral add to 360° (think about a rectangle). Therefore, we can form the following equation to solve for angle z:

`z + 112\° + 76\° + 78\° = 360\°`

↓ executing the possible addition

`z + 266\° = 360\°`

↓ subtracting 266° from both sides

`\boxed{z = 94\°}`
