Answer:
<h2>D = 28°</h2>
Step-by-step explanation:
To find angle D we use tan
tan ∅ = opposite / adjacent
From the question
DE is the adjacent
EF is the opposite
DE = 13
EF = 7
tan D = 7/13
D = tan-¹ 7/13
D = 28.3°
D = 28° to the nearest tenth
Hope this helps you

C? Is my guess, if your following the pattern.
It will be 145 degrees.
If the top line is above the x-axis, it could stop and have an angle of 35 deg between quadrant 1 and 4.
If the bottom line is below the x-axis, it could stop and have an angle of 145 degrees between quadrant 2 and 3, because it is a supplement of 35 degrees.
The answer is false because there is 360 degrees inside a circle and any part of that is an arc
