Answer:
64°
Step-by-step explanation:
<em>So supplement angles are equal to 180, so first our two angles added together will be 180:</em>
x + x = 180
<em>Now one of these angles is 6 greater than half:</em>
x + (x/2 + 6) = 180
<em>Then we will solve for x:</em>
x + (x/2 + 6) = 180
x + x/2 + 6 = 180
x + x/2 = 174
x = 174
x = 116
<em>Plug it back in:</em>
x + (x/2 + 6) = 180
/\
x/2 + 6
(116)/2 + 6
64
<em>To check:</em>
116 + 64 = 180 ✓
<span>Complete the following direct proof.
1) Triangles are the only polygons with three sides.
2) The polygon has three sides.
3) Thus, triangles are polygons.

Equal angles are congruent angles.
Answer:
D 21.80°
Step-by-step explanation:
Let x = measure of the angle
Tan x = 12000/30000 = .4
Arctan .4 = 21.80°
