Answer:
62.5%
Step-by-step explanation:
Total number of animals in a group= 5+3=8 animals
Number of rays=5
Since we only have 5 rays out of the total 8, to express the number of rays as a percentage of the total animals, we divide the number of rays by the total animals then multiply by 100 to express in percentage as needed in the question
Percentage of rays=
Therefore, the percentage is 62.5%
Answer:
see explanation
Step-by-step explanation:
Using the tangent and sine ratios in the right triangle EFG
tan60° = =
=
( multiply both sides by EG )
EG × tan60° = 28 ( divide both sides by tan60° )
EG = ≈ 16.2 in ( to the nearest tenth )
--------------------------------------------------------------
sin60° = =
=
( multiply both sides by EF )
EF × sin60° = 28 ( divide both sides by sin60° )
EF = ≈ 32.3 in ( to the nearest tenth )
