HELP PLEASE I GIVE POINTS​

Answer 1

80 Degrees

Explanation:

A triangle equals 180 degrees when all sides are added together, so here we need to first add the angles of the ones we have available.

30 + 70 = 100

Now, we subtract to find out how much more we need...

180 - 100 = 80

Answer 2

∡ a = 80°

Explanation:

the sum of the interior angles of a triangle is 180 degrees

a + 30 + 70 = 180

a + 100 = 180

a = 80
