Answer:
D
Step-by-step explanation:
Using the cosine ratio in the right triangle.
cos66° =
=
( multiply both sides by x )
x × cos66° = 13 ( divide both sides by cos66° )
x =
≈ 32.0 ( to the nearest tenth )
Answer:
x = 9/4
Step-by-step explanation:
Locate point G on segment DE so that DG = 1 and GE = 4. CG is parallel to AD, so ΔCGE ~ ΔABC. Corresponding sides are proportional.
AB/BC = CG/GE
x/1 = 9/4
x = 9/4
_____
<em>Additional comment</em>
Using the given triangles, you can write the proportion statement as ...
(9+x)/x = 5/1
We judge this to take more steps to solve, so we prefer the method shown above.
5/36 I believe is the answer
