Hope I could help :)
Answer:
BC ≈ 3.3
Step-by-step explanation:
Using the tangent ratio in the right triangle.
tan A = 
, that is
tan20° = 
= 
( multiply both sides by 9 )
9 × tan20° = BC , then
BC ≈ 3.3 ( to the nearest tenth )
Answer:
5.8
Step-by-step explanation:
Side KI is proportional to HF, and as we know GH is proportional to JK, we can make a proportion. x/31 = 8/43, 43x = 248, so x = 5.767, which rounds to 5.8
X = 4
3 divided by 4 = .75
