Use photo math it works very well!
The building blocks of geometry would be point line and plane.
Answer:
The vector equation of the line is
l(t)= "-3,3,-5" + t "-2,-4,-4", where t is a parameter.
Answer:
BC ≈ 8.9 units
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos36° =
=
=
( multiply both sides by 11 )
11 × cos36° = BC , then
BC ≈ 8.9 ( to the nearest tenth )
200mm is the right answer
