Question

Anyone mind explaining this?

Answer 1

j = 59°

k = 104°

l = 95°

m = 102°

Explanation:

Each exterior angle is supplementary to the interior angle next to it.

So, to find the measure of each exterior angle, we need to subtract the given interior angle measure value from 180.

For j:

180 - 121 = 69

For k:

180 - 76 = 104

For l:

180 - 85 = 95

For m:

180 - 78 = 102

Answer 2

see explanation

Explanation:

In any quadrilateral , the exterior angle and its corresponding interior angle , sum to 180°

Then

j = 180° - 121° = 59°

k = 180° - 76° = 104°

l = 180° - 85° = 95°

m = 180° - 78° = 102°
