Answer:

27° (as an integer)

Step-by-step explanation:

From the figure given;

Triangle BCD is a right triangle;
We are given the two shorter sides;

DC = 8 units

BC = 4 units

We are required to determine m∠D

We need to use the appropriate trigonometric ratio;

In this case, DC is adjacent and BC is opposite to m∠D

Therefore, the appropriate trigonometric ratio is tangent;

That is;

Tan m∠D = BC ÷ DC

= 4 ÷ 8

= 0.5

Thus;

m∠D = Tan^-1 (0.5)

= 26.57

= 27 (as an integer)

Thus, m∠D is 27°
