Answer:
The correct answer is d because m<3 is supplementary (meaning the angles add to 180°) to m<4. It's easy to spot two supplementary angles because they will form a linear line.
The attached diagram is an interpretation of the question.

The distance AD is found by Pythagoras theorem, with
AD=sqrt(BC^2+(AB-DC)^2)=sqrt(21^2+2^2)=sqrt(441+4)=sqrt(445)
=
21.095 (to the third decimal place)
Point slope form
y<span> – </span>y1<span> = </span>m(x<span> – </span>x1<span>)
</span>
so equation
y + 5 = 5/7(x - 8)
