Answer 1

Answer:

The answer is 160

Explanation:

Because the sum of angles in quadrilateral=360⁰

that's why fourth angle is 160⁰.

This is correct answer

Answer 2

Hello!

Measures of three angles = 30°, 70°, 100°

Total sum of angles in a quadrilateral = 360°

$fourth \: angle = 360 - (30 + 70 + 100)$

$= 360 - 200$

$= 160$

So the answer is 160°
