1.

The number of degrees in a quadrilateral added up is 360.

The number of degrees in the other angles are 108, 72, and 81.

108+72+81 = 261

To find the last angle, you subtract the number of degrees of the other angles from 360.

360-261 = 99

The measure of unknown angle is 99.

2.

This problem is very similar.

Add up the number of degrees in the other three angles.

95+121+59=275

And you subtract 275 from 360.

360-275 = 85

The measure of the missing angle is 85.

it has the same slope and a different y-intercept

hope this : )
