This is the concept of trigonometry, the height of the tree will be given by:
tan theta=[opposite]/[adjacent]
theta=80
height=h
adjacent=5 m
hence;
tan80=h/5
hence;
h=5tan80
h=28.36 m
Answer: D
Step-by-step explanation: ?
Answer:
yes
Step-by-step explanation:
divide each by 7 =
21/7 = 3
28/7 =4
35/7 = 5
3,4,5 are always a perfect triple, and multiples of 345 are perfect triples as well. Therefore, they are sides of a right triangle.
